Dear Z Community,

I need to use an entry in a related list as a trigger for a further action. (every time a Contact is linked to a Campaign)

The problem is, that relationship already exists in CRM (Contacts linked to campaigns) but that relationship is not selectable as a trigger for a workflow, since it isn't a field in either module. The relation is selectable when creating reports, though (it's the only visible place I found in CRM) 

the problem is, if I interlink both modules with a multi- lookup field and generate a interlinked module (contacts x campaigns), I kinda "repeat" the existing "underground" connection and then I get 2 identical, related lists in both modules, Contacts1 and Campaigns1 that make different relations.

Is there any way of detecting the "original" connection without having to manually interlink both modules again?

Many thanks in advance.
