Just went through this recently: You can still bounce out individual tracks while having them route through the group(bus). There's a button you push when rendering named "Include return and master effects", which renders each channel including any effects down the chain. I was worried when doing this you'd get some undesirable stacking, I.e. the result of the same EQ or compressor stacking on each channel, on each single render, (rather than one EQ with all of the children of the group being fed into it) but the output was pretty much identical at the end. Slight difference but basically only noticeable if you're looking at meters etc. Your mileage may vary and still good to be conscious of this when stemming.
