It would be nice to have a tool to apply an xref to all sheets in a sheetset. In addition to having an option to select which sheets in a sheetset would receive a reference file. Right now, we only have the ability to attach a reference file to each individual sheet. Say I have 20 sheets in a sheet set, and I need to change the date in a titleblock for each sheet, it would save a lot of time to attach a reference file containing a date to the entire sheetset instead of changing each of the 20 individual sheets.
