I work exactly the same way. Just as a piece of advice, don’t go into the single tracks too early. In a live recording, the big part of the work is often “corrective” adjustments, like pulling certain annoying frequencies, and these should be pretty much the same for all the songs.
My workflow: Put a Hipass on almost everything. Try out Lowpass Filters for better channel separation. Normalize, get an initial balance using the trim knobs, do the editing for the whole show. The Audition feature (a) and the split (s), trim start (j) and trim end (k) command are your friends here. Create region markers for each song and label them. Polarity, basic EQ. After that, set up gates and compressors. Use the region gain feature (Alt+6/Alt+7) if there are drastic changes in level between the songs.
In the Master Bus, I usually put a spectrum analyzer, a multiband compressor, a normal compressor and a limiter before even starting editing. But that’s a matter of taste.
Only after having done all these things, I save individual snapshots for each song. In my experience, this saves you a lot of work and helps to achieve a more consistent sound throughout the show.
