I have been hunting for such a solution but have a small problem. I am trying to follow the suggestion, but get an error message when I try and use the new tag type that I set up.
The error appears in a small pop up window titled: "The Master Genealogist" and says:
"Unknown member CNTWITNESS. 1 FRMEVENTS.MCHECKEXISTINGROLES
and then has [Abort] [Retry] [ignore] buttons.
If I continue, there is no witness tab for the event to add other individuals, and no obvious answer in the help file.
I am a relatively new user and suspect that I have missed something when I created the new tag type. Is it possible to get more detailed info on the various elements of the new tag type.
Note: I just upgraded from UK v6.0.0 to v6.07.00
