First off, I said “try the following” Seems like it should work, but no guarantees.
Why would a different BAQ be needed? Update the BAQ like @Hogardy said.
If you absolutely want two separate (but identical) baq’s, edit the exported Dashboard, renaming references of the "old BAQ name " to the “new BAQ name”
One last question (hopefully) - how can I delete a dashboard? I tried the X and I tried right clicking on the left pane and choosing delete. Any time I do that, it’s still there.
