How do I change Quartus to use a different .stp file?

I'm using git and I changed to a new branch and then back. SignalTap is now using the wrong .stp file.

How do I change the .stp file that my Quartus project uses? (I want to be able to switch from one to the other).

I'm using Quartus Prime Version 22.1std.0 Buil 915 10/25/2022 SC Lite Edition
