All of this is fantastic, thank you so much! I'm actually creating my spreadsheet right now, as I'm typing this. I will most likely have to add another column to the crossover sheet - AUs. My fandom has hundreds of them, in various genres, both open and closed. So, I'll have column one for AUs - whether it's the original OW universe, ATF, Trek etc, and column two for crossovers (say, ATF AU, crossover with e.g. White Collar).

I just wanted to clarify what you meant by saying "Below the main entries". Does this mean that this goes below the table? If not, where would this section be placed?
