Toggle or Add-On to set default dungeon mode?

Giraffon

I'm pretty sure there is no such thing at this time, but I would love to see a default dungeon mode setting that you could set. Obviously this request is inspired by the recent dungeon event. Going after mystery boxes had me wanting to stay away from vet dungeons. Every time I picked Groupfinder it defaulted to random vet dungeon. I always had to remember to switch it so I could run the dungeon quickly in normal mode. It was annoying.
