Stylistic Sets + Tabular Figures

I'm sure there's an easy solve for this, but I haven't had any luck looking around on my own. 

I'm working on a typeface that has proportional lining figures as the default, with a stylistic set for a few alternates (see image below). I'm also working on tabular figures, and want to create a tabular version of the stylistic alternates as well.

I'm not sure what the best practice is for setting this up in Glyphs. Is it possible with suffixes (.ss01 vs .tf) or is it better to create new glyphs and write them into the tnum substitutions myself? 



Thanks
