Category Shortcut Key Suggestion

Under Menu->Tools->Categories, is there a way to assign category shortcuts to a different key other then Ctrl+F(x) ?   I would much rather prefer just using the number 1 2 or 3 key for assigning categories.  Much easier and less cumbersome. If you go to Tools-> Shortcuts, this allows you to assign any custom key to the settings, but for some reason in the categories menu it only allows you to choose from preset keys.  Why not allow custom keys there as well?  Is there a file I can edit to allow this?  Any suggestions?

Unfortunately it is a little limited and there is nothing you can change Andrew.

Maybe this will be considered in a later version if there is enough interest. You have my vote.
