Role Grouping; Server groups but for roles

I've come to suggest an idea which has most likely been suggested multiple times before. The idea is simple in which we already got "Server Grouping" in where you can group servers together into a file icon. What if we could group roles in a similar way, this is to keep a server's roles tab much more organized than it already is and can give easy access to roles. An example of what I envision it would look like through text would be something like this:

(It would look slightly like server categories)
Role Group #1:
   - Role #1
   - Role #2
Role Group #2
   - Role #1
etc.

This would solve a major issue in some large servers having so many roles that it takes a good while to find what you're looking for, this is especially prominent in servers that use custom roles for members and making a large mess in the process.
