Have you guys considered a "cave mode" for deco calculations? I don't know what to call it, but my thought was to make it something similar to the @+5 but actually regarding exiting the cave. It won't work for all caves (high flow, traverses, non-standard dives, etc) but since you know the profile taken to get in you know the theoretical profile to get out and should be able to have a TTS after the exit is made. I was doing a dive in "Hole in the Wall" (a no-flow FL cave of moderate depth 70-100ft) and had a fairly extensive bottom time. The average depth was much less accurate than I planned, so I was "flying" the computer. When we turned, we had gas but were afraid of racking up too much deco. If the computer had a function where it reversed the profile we took to get there (time and depths) and told us about what the total deco stop time would be if we turned then it would've saved us a lot of hassle. We had just breached NDLs by a few minutes (I think we had like 7min TTS, at 90ft) but ended up with ~45min of deco. The computer estimating it would be nice.
