Hi all! Good news - we recently started rolling out linkable comments! 
With linkable comments, you will be able to easily share and reference existing comments in Asana. Next to each comment, you already have a drop-down menu allowing you to delete and edit your comment - going forward you will also have the option to “Copy Comment link”. Clicking this option will automatically copy the link to your clipboard - from there you’ll be able to paste this link anywhere else in (and outside) of Asana.
We hope you enjoy this new feature as much as we do!
