I have a little over 800 photos with tags in shotwell. Recently, hierarchical tags have been added.

Now I want to reorganize my tags, e.g. I want a "People" tag and subtags of "Mom", "Dad", etc. Is there an easy way to do that, which doesn't involve me draging and dropping all the tags to their parent tags?

I have quite a lot tags and since every time I drag and drop a tag, I can only select one tag I want to move and I have to wait for shotwell finishing that operation. After it's done that, the list view scrolls back to the top, which means I have to scroll back down all the way to "People".

Example for clarification, pretend tags were directories. I want to do

mv tags/{mom,dad,brother} tags/people/
