I would like to have any race that's in our collection to be added to the race group drop box for homebrew subraces. That way subraces won't be spread out throughout the race selection screen in the character builder. All the races could be neatly organized into their own drop down folders, just like the official races of elves/dwarves/etc.

For the following pictures, if the Mousefolk race in my collection was available for the race group, then the Mousefolk race would have a drop box and reveal all the subraces in one spot. Instead, my players have to search through my collection for any mousefolk. If they are browsing, there's also no way to know there are only two subraces, they could waste time looking for a third. For time saving reasons along with overall cleanliness to the race selection screen, I would like this feature to be added. See pictures below.

Even for a race that has all of the subraces together, it still builds a lot of clutter. See picture below. This is something that including all races in the collection to the race group drop down box, instead of just the official races, would help.

It looks like someone already requested this here:

It would be great if you would add your additional description to that and vote!

Thanks. I have transferred my post in the form of a comment and upvoted that request.
