Try using "Favorites" in the local data filter, maybe that will give the functionality you are looking for.

Note that these Favorites will disappear if you close the Graph Builder window without saving. To have access to your favorites later, save the Graph Builder window before closing (save it to a file, add it to the data table, save it as a script, etc).
If you want to apply these favorites to a different analysis window, that takes a bit of scripting work. Save the Local Data Filter script from the Red Triangle Menu, and it will include the Favorites within that script. Add that to the script for the analysis you want to add the favorites to, and they should appear there.
