One work around to achieve this is to include the word “split” in your User performances each time you create a new performance that contains a split. By doing this, you can then utilize the search box (upper right of performance home screen with magnifying glass next to it) to search for any performance that contains the word “split”. Sometimes you just have to get a little creative with this powerful new system. Something that should come natural for us musicians-

Hope this helps.
Question: I've created a few Perfs of my own and I'd like to be able to search for them using "splits" as a sub-category. Can I create this sub-category myself somehow? Also, I can't seem to find how to change any attributes of my own perfs to a different existing category or sub-cat. Help.
