Using a MindMap node to populate a data element?

Hello all, I’m new to Agilian and am trying to determine if it allows the following:

I want to perform discovery using MindMaps, in which I generate a diagram of all the document types being used in an organization, along with the metadata that applies to each document type (appearing as sub-nodes below each document type). I then want to create BPMN data elements that correspond to the metadata model for each document type. These data elements will be used to drive gateway logic, and will also be used to populate a series of grid diagrams.

Based on what I’ve read so far, it seems I just need to set tagged values for the data element that map the the appropriate MindMap leaf as a model element. Is this right? Is there anything I need to know about the capabilities/limitations of this approach?
