This seems like a no brainer, as it adds no value to the Marketing team to see the GUID of all the synced Lookup fields from the Dynamics CRM integration with CRM.
So, to see an actual value, well, it makes 100% difference in the product.
Not sure when this was marked as "working on it" (I suspect it was on or before April 20, 2016, since that's the last update date), but can we get an ETA on when this capability will be available?
