I'd like to be able to easily find a custom peak interval within a single workout (i.e. not the Peak Performance overall; just within a single workout analysis).

For example. I use CTS programs and they have an FTP field test that requires 2x8 min intervals. These aren't terribly hard to see in the analysis, and I can create and save a custom interval. But sometimes the TP sliders aren't very precise.

As another example, I also do a sprint test every so often, with several 150M sprints repeated. These are very difficult to select in TP because 150M is a short interval. And I do 6-8 of them during the workout. I'd love to be able to just "ask" TP to show me my best (where "best" could be fastest, highest avg power, lowest time...whatever) 150M interval in the workout and have it automatically find and highlight it.

As an alternative, though not quite as good, it would be nice to be able to set the selector window to a custom interval and then slide it around the graph. E.g. set and lock the selection window to 150M on a distance-based graph so I can slide it around and manually identify my best 150M interval (or whatever time/distance I select).
