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.
