AME Watch Folder with Image Sequences

Hypothetically - say I have 5 renders in my AE queue. The 5 renders are all PNG sequences that all render to their own sequence folder. The individual sequence folders are within an export folder. If AME is set to watch that folder, is it possible for it to know when a PNG sequence has finished so that AME can render?

Also, I've noticed that AME by default sees image sequences as 29.97. In order to change it to the correct frame rate, I have to manually interpret the sequence. If I have a watch folder going, how can I force it to interpret as 30 or 24 or whatever it's supposed to be?

I'm currently working with 30FPS for this particular project. If I skip interpreting the footage, and just have it export as 30FPS, I end up with 4 extra frames over 3600 frames. That's a problem because all the footage needs to stay in sync.

Ideas?
