Applying Workflow Logic to Master Record after a Merge

Hi all,

I am trying to determine if I can see what records have been merged inside of CRM2013.  I have located the merged field in the database which is a flag that looks to be set on the subordinate records to True after a merge.

For example:

Record B (Subordinate) is merged into Record A (Master).  Record B has a Merged field that is now set to true.

What I really want to do is try to create a workflow in CRM2013 that performs an action on the Master Record A in the example above.  What I have found, however, is that you cannot use the Merged field in a workflow, view, etc. I am trying to figure out how I can do something very simple like writing a flag to the Master Record.

Any ideas?

Thanks very much in advance!
