Is it possible to assign attributes to an issue, EG a label, depending on who the issue reporter is?

[Mick C]

I have various stakeholders who add tickets into the backlog for triage. I would like to add a label automatically so for example if MR X created an issue then it would have a label on it "MR X"

or whatever combination of that can work. I'm sure you get the picture.

https://marketplace.atlassian.com/plugins/com.codebarrel.addons.automation is probably your best bet. Or in JSD you can try using the integrated automation.
