Cube drafting with snow lands

Hello all!
This is the first time im posting in this forum, so please help me in case I do this wrong.
My issue is, that I want to use snow covered basic lands instead of regular basics for my own 360 card cube. In paper this was easy to achieve but I want to test draft this cube in Forge. Has anyone already done that and can tell me how to do that? Ideally I'd like to click on the 'Add Basic Lands' button in draft editor to choose my own set of snow lands in order to add them to my deck. Also having access to the full deck editor card collection would be helpful while constructing the draft deck I guess.
I don't care if the AI is not able to use Snow Lands.
I'm using Forge v1.6.30.
Thanks all for your help and for your time and ressources you're investing for people like me. =)
