Prevent Duplicate Values in a number custom field

Since we cannot auto generate a short Reference ID for tasks (the url is not user friendly), I am manually creating a 4 digit unique reference ID for tasks. These Tasks are for 1 team but across several projects. I am currently doing this manually.

I would like to be able to create a rule on custom fields that are Numbers, “no duplicates allowed” that way I don’t create duplicate Reference ID’s.

(Of course this would not be needed if auto-creating a short reference ID was available)

Hi @Ali_Higgins and thank you for sharing your feedback with us!

I totally agree with you that this would be super useful. I’ve gone ahead and made a task to share your feedback with the team! In the meantime, don’t forget to upvote for the suggestion!

Have a great Friday Ali!


Nice idea.


thanks for the info @Natalia. Is there a way to see what items are on Asana’s delivery roadmap and expected delivery dates?

Sadly no, no public roadmap. Member of Asana Together get some information in advance, a couple of days at most.

Has there been any movement on this? could really do with this feature right now aha
