Our users need to know the source module in a worksheet in order to be able to use the Addin Excel extension. It's possible to see it in a card on a Board, it is regrettable not to offer this information also in a worksheet.
I guess end-users should not be so much concerned about the source models. Why would they use the excel-addin if they have a worksheet? But yes, it is a great bummer for page builders and model admins.
