Connector back Numbering

Looking for a way in a drawing to show the back side of a connector with all of the positions for where a wire could be to be numbered. So in a drawing once the connector is shown (like the ide view from the flat harn file) I can add that photo along with a table to show where each wire goes in the connector.

I know I can just show a view of the rear of the connector but I don't know of a way to add numbers or letters and make it something that I can save and just drag in when needed.

Added a picture of what I'm looking to do.
