Multiple Jiras in a single GitLab instance


We have consolidated our GitLab instances, so we only have one robust server now.
But we still have multiple Jira servers WW, depending on the teams.

In, it looks like you can add only one URL.
I would have expected to be able to set this up at project or group level, as for Jenkins.

I found an old issue which seems almost dead about this.

Is there a way to do this from the CLI ?
