Is there an Undermine Campaign Skip?

Excited about the real Season 2 hitting on Tuesday and being able to finish Campaign to open up zone for alts. Grinded through the usual Undermine kill-a-bunch-of-something quests and now ready for the final effort. And it’s a damn dungeon. Apparently NEXT week we get option to do that in solo mode.

Assuming this wasn’t a strategic decision, it’s just that Blizzard is still trying to make things work.
