Rename Trigger/Swap set?

Hello, using the new CA CC2018, totally love the new improvements!

Have a question though- I have tried to rename trigger/swap sets I have created (shown on the "trigger" panel), but can't seem to find a way to do it.

For example, I want to rename one swap set for my puppet's right hand "right hand", but don't want the illustrator layer to be named "right hand" (less titles, words, easier to rig and know where parts are). I have tried double clicking the name in the trigger panel, as well as looked in the edit menu, but no luck so far... is this possibly a bug?
