Fusion Drive - How to resize partition?

Hello there.

I've been searching google for many hours on how to resize (make it bigger) fusion drive bootcamp partition, without doing it manually (deleting/creating new)

Since i have MANY games and such, I dont want to reinstall / redownload them again.

I can't use Camptune, it doesn't support fusion drive.

Is there a program out there supporting resizing for fusion drive?
