Alright so here is what I am trying to accomplish, I rarely but sometimes someone will go back and look for a document that would have been added to the repository via a Workflow using information from a Form but that document can't be found. Today, for instance, I can track the document through the Forms process and then the Workflow process and it says it made the document but I can't find it anywhere, even in the Recycle Bin.

Luckily, these are simple to recreate, find the Workflow and plug the Instance and Submission IDs into the setting section of Retrieve Business Process Variables and it works beautifully. However, I am trying to automate this for some people via Forms and I can not get Retrieve Business Process Variables to allow any type of custom token to be used. It accepts ones made by default via certain activities but I can't get it to used anything from another Retrieve Business Process Variables or an Assign Token Value. 

Is there a way to feed tokens generated by a Retrieve Business Process Variables or Assign Token Value into maybe a "Global" or "Input Parameters" or something else?
