I have a title block in my drawing template and sheet format that is composed of several Blocks so that the title block elements can be easily rearranged.  If I create a drawing and add a second sheet, I get the following annoying popup warning:

If I click 'No', when I add a third sheet (using the same sheet format that was used to add the second sheet) no error message appears.  If I click 'Yes', the blocks are all duplicated with the suffix '_1' added to the names, and adding a third sheet has no problems.

I can't have this popping up every time one of my users wants to add a second sheet.  Short of exploding all the blocks, does anyone know of a way to eliminate this warning?
