Mark existing tag as automatic tag?

I am still in the process of importing a lot of older projects from Citavi. That software also grabs a lot of automatic tags when adding to the Citavi library. When those are imported into Zotero they are naturally registered as user tags. I really like the separation between automatic and user tags that is possible in Zotero and find it quite useful to switch between. So i don't want to delete the imported tags, but ideally want to mark them as automatic myself. Is there a way to do so? Perhaps through a plugin?
