So far as I know, asana doesn’t let you at-tag attachments, but:
- You can achieve a similar (though less pretty) result by copying and pasting the address of attachment (see visuals below)
- The disadvantage here is the long, messy-looking link, as asana doesn’t allow you to turn words into links. You can make your link cleaner using bit.ly (as suggested by @Sebastian_Paasch here)
And paste!
