CC Collaborators/File Sharing

Hello. I have a question about CC Collaborators. I share my Cloud files with a number of other users. For the ones that use Creative Cloud Desktop, it seems that when I invite them to share my files, the files automatically sync and add to the storage in their CC account. I have a large number of files (over 70 gb). Is there a way for those users to share/have access to the files only through CC web and not have them added to their CC accounts. a lot of them are designers and refuse to share files through my Cloud because it will fill up all of the storage on their accounts. I would like them to have access to the files without adding to their storage since the files are already stored on my account. That way, they can download my files, work on the files offline, and then add the edited files back to my CC account. Is there a way to do this? Thank you.
