Mannequin - Selling as a set

[Dustytome]

I actually came here trying to find out how you even turn that on so you can view those items in a search. I'm not finding the option.

When you click an item on the mb to see all the listings for it, at the top right there should be a little bubble button that looks like a funnel that's for advanced options and under that you need to disable the option to hide items sold as sets. Last I checked it kept resetting itself automatically too.
