Friendly URL's

[GriefCode]

Hey,
I got the group collabriation add on to my IPB and i got the friendly urls activated.

However, my goal is, to overwrite an url from the group collaboration so its dedicated to the community.

The normal friendly url:
https://gamers.host/gc/cat/category-??

Its created from:
https://gamers.host/index.php?app=collab&module=collab&controller=categories&category=123

What i try todo, is pointing this url:
https://gamers.host/sea

to:
https://gamers.host/index.php?app=collab&module=collab&controller=categories&category=2

That url is probably overwritten by the first one: 
https://gamers.host/gc/cat/category-??

Is there a way to avoid the overwriting by the other rule without deleting it? I didnt tried yet to delete it 

Regards
