How to disable flex time for a specific slot and replace it with mid-roll filler?

[Zachary-Rude]

I've tried setting up some mid-roll filler for certain shows in my Tunarr channel, but because flex time is being auto-generated, the mid-roll filler gets ignored. Is it possible to disable flex time for certain slots so that midroll filler can show up? And if so, how do you do that?
And as a bonus, is it possible to have a bumper show up right before and after flex/midroll time? (e.g., the "we'll be right back after these messages" kind of bumpers)

Flex does not suppress mid-roll in the 1.3.x scheduler. Tunarr applies the mid-roll split first and then fills whatever time remains in the slot. If no break appears, the usual cause is the mid-roll eligibility settings rather than the flex item.

For the show slot, check this sequence:

1. Open the slot, go to Filler, add the desired filler list, and enable the Mid type. Assigning a list only on the channel's Flex page, or selecting only Fallback, does not make it a mid-roll source.
2. Open the Mid-Roll tab that appears.
3. Lower Minimum Program Duration below the episode length. Its default is 60 minutes, so normal 22- or 45-minute episodes are skipped.
4. Choose a break point that actually falls inside the episode. For a 22-minute episode, the default 30-minute interval produces no break; use something such as a 10-minute interval or a 50% percentage point.
5. Set the break duration and regenerate the preview.

The current setup is documented in Tunarr's mid-roll guide, and the feature was already present in v1.3.0 via #1736 and #1832.

To remove the remaining flex for one slot:

• In Time Slots, open that slot's configuration and set Pad Times to Do not pad. This is a per-slot override.
• In the Slots Editor, change that slot from Fixed duration to Dynamic with the desired program count. A fixed-duration slot is defined to occupy its full duration, so Tunarr must fill the unused portion. Also set the schedule-level Pad Times to Do not pad if clock-alignment padding is creating additional flex.
• If you want to keep the fixed start/end times, assign a filler list to that slot as Fallback. That does not remove padding, but it replaces the otherwise generated flex with your selected filler.

For the bumper part, the slot filler types are:

• Head/Tail: start/end of the whole slot
• Pre/Post: before/after each program
• Mid: inside the program at generated break points
• Fallback: leftover flex/padding time

There is not currently a separate “open every break” / “close every break” wrapper around generated Mid or Fallback blocks. Pre and Post surround the program, not each mid-roll break. For an exact “we'll be right back → ads → welcome back” sequence, the reliable options are to make that sequence one prepared filler clip, or use explicit filler slots around a known break in a sequential/time-slot schedule.
