How do you handle alternate signoffs?

I've just learned that our Eng. Mgr. will be out for two weeks and he's instructed me to designate another user to approve/signoff drawings while he's gone.  My immediate option is to go through the workflows and change a lot of permissions and notifications now, then change them back when he returns.  Tedious, and certain that I will make some errors that will create problems/confusion.  I'm hoping there's a better way.

I could create alternate workflow paths with conditions, but those conditions would be based on variables and other factors that are tied to the individual files.  That would not work, as I want to be able to 'switch' the paths for all files based on a value or variable that would affect all files, then switch it back later.  As far as I know, there is no capacity for Global Variables, or for workflow transitions to react to them even if they existed.

Any suggestions?
