Question title + Tag

Hi all,
I'm trying to figure out how to do this manually:
I know how to auto-number the questions per block, but I don't know how to put a tag (#2) at the end.
I've been trying to click and edit, right click and test a few options, but I just can't do it.
I saw it on pre-made Qualtrics questions, and now want to do it for myself because it makes the export data very clean and easy to distinguish without the whole question on the header.
Appreciate the help!
