Project specific icons

The list of icons is so very long and the Recently used is at the top of the list. This means I have to Right click the icon, scroll all the way up to the top to get to the ones I’m using. I use a few specific icons. This means there are a whole bunch I don’t use. I would like to be able to create a specific set I’m going to use in the project. I’d like to be able to use that set in multiple projects without having to recreate it.

Thank you for considering my request.
