Automation Blocks - List Reduction
I'm looking to reduce a list from a spreadsheet and don't know how to do it.
I've got a .csv where column B is the 'type' of sequence that the shot belongs to.
Column C is the the actual sequence name and Column D is the shot name.

This is my current block set.

The last two "in list" blocks add the last selected item to the top of the list with a space. (Super handy, but I can't figure out an easy way to exclude the space from actually being selected.)
It creates a list that is every single line of the .csv

How can I reduce all the "same" sequence to a single item? Or if I had many "reduced" sequence initials that would get pulled if they match the "if" block?
