Can I Rename/Amend the Name of a Rate Set?

Thanks to SB for the Rate Sets feature.  Creating and applying differing rate sets to our various corporate and institutional clients has been a real time saver!  Love this feature.

Um, that said, I’d like to tweak the names I eagerly assigned to our rate sets when this feature first rolled out.

Can I amend the existing rate set name and save it without impacting the countless time entries and matters that are already tied to the old rate set name?  Or is the name locked-in?

Thanks.
