Reference Current Parent with Button on Child

There is a way to have a button on the Daily Report to set the current user's "Focus" to that daily Report Record.  Then when clicked it would refresh the Parent Daily Report record and show the embedded report of unlinked Purchase Orders.  If relevant (and I'm just guessing here) that embedded report could be filtered for just the Purchase Orders created by the current user.

Then now that the child table is exposed by a form rule that knows that the Daily Report is in focus the child record table would have a button to link to the focus Daily Report. 

The page would refresh and the Daily Report record would now show one more linked PO and one less orphan PO upon each successive click.

This can be set up with an hour of consulting time as they step by step of how to do this is a bit too complicated to do on his forum.  Please contact me at mark.shnier@gmail.com and I can give you a quick demo of the look and feel of this and you can decide if it's worth investing on a hour of consulting time.
