Is there any way to remove assigned issues from timesheets?

Hi, 

We need to assign users to request queue issues, but don’t want them to add time on the issue or see the request/issue on their timesheet. Users will add time on a task in the project where the issue is. I see a 4 year old post about this topic- 

I was wondering if there’s been any updates since this post that would allow me to restrict users from adding time to issues. Currently, we’re exploring creating individual teams and assigning that to the issues, so issues won’t show on timesheets. But I wondered if there were any other ideas on this.

Thanks
