Search function for Assigned commands?

I would like to see the ability to search for a command rather than just eyeballing through all 5 screens of command options.

 

With a smart search for when you don’t know the exact name of what you’re looking for.

 

Yes, that would be an issue. But some game I've played, I've found the command I want, then months later can't remember what section it was in. Searching a generic keyword at least gets the process started.
