Data from multiple sessions

I have come to realize that there are faint objects that require long periods of integration, even with my very fast, F2 scope.

So, when I accumulate data over several nights (yes, from the same exact spot with the same exposure time, temp, etc.), and assuming I take more flats each session, how do I integrate the flats from successive sessions into APP?  In fact, what is the best method of combining the lights?  

I've never tried this but it's time to try new things.

The best way would be to separate the flats of the different sessions. So you load the data of session 1 as session 1 and assign the flats of that session to session 1. And so on.

If, upon close inspection, the flats look exactly the same you can try to combine that data and use it for all sessions. Usually a good flat requires like 15-20 frames.
