Is there a way to bulk delete priority values from the priority field?

Question

I imported a project from another cloud instance using the CSV import function.  Unfortunetly, I messed up the priority mapping and because of that imported over 1600 priority values incorrectly.  Is there a way to delete priority values in bulk via Jira Cloud, Scriptrunner, or some other plugin?  Doing it by hand one at a time is pretty time consuming.

Thanks,

I also had the same issue. It would be great to have a bulk delete of priority fields. 
I'd say it's when you import from another PM system such as Linux. I'm currently manually deleting...

Oh, I see. I did not fully grasp your problem.

I did not find anything in the REST API for the global priority value list other than GET commands. Nor do I see a way to delete multiple values through the UI.

I am talking about built-in Priority field.  How do you delete more then one from the list at a time?  There are 1600 values in the field that the user can select from and I need to remove almost all of them and would rather not have to hit the delete button 1600 times.

Thanks!
