Make merchant selection, at store level, same as at factory level

[patagonia]

I like the way the new V3 lets us mark our merchants. It is a big grid, and the button turns dark grey when you click the merchant. EASY

Can you use this same layout/function when selecting merchants to add to a particular store?

I hate the way I have to scroll down the list and look for the check boxes.

Should be easy peasy right, since it is already done at the factory level?!! ;P
