Merging duplicate tasks should put a link on the master task

If task A is marked as a duplicate of task B, I want a link on Task B back to Task A.

Here’s my use case. Users use Asana as a ticket system for existing software. Often there are duplicate tickets submitted, but they hold slightly different information. If I mark task A as a duplicate of task B, i need to copy over the relevant info of Task A into Task B, else marking it as a duplicate is effectively no different from deleting Task A.

I think there used to be a line in the history of task B that would tell me this happened, but I don’t see this anymore.

Here’s a quick mockup of what I’m imagining:

The closest existing use case is this but that’s not what I mean. It’s also NOT this because this is creating duplicates of an EXISTING task. I’m talking about marking an existing task AS a duplicate.

Yes, I have the same issue.
I don’t see a backlink either, although it is mentioned in the function that it would create backlinks to merged tasks in the main task. I don’t see a comment, neither a remark somewhere in the main task.
What you made @matt21 is maybe a great way of refering back to merged tasks.
