Our business has a number sub-businesses which we have setup as sites.

Most problems get fixed in the home site, but sometimes we need to escalate certain requests to HQ site.

How does a technician escalate a ticket to a site they are not a member of?  Or preferably, what business rules can we use to auto assign a ticket from home site to HQ site based on ticket level 3+ and back again at level 2-.

This feels like such simple functionality but I am not sure how to overcome it!  Welcome your advice!
