I have AspDotNetStorefront Multistore 9.1.0.1/9.1.0.0. There are 3 stores running on this application/database. WITHOUT the Vortx Plug-In, is it possible to have a MOBILE skin for each of my sites?

I'm currently able to alter MobileSkin_1, but I can't figure out how to point a store to each skin when creating MoblieSkin_2 & MobileSkin_3.

Thanks for any help.
