Can I build this brick wall in Glyphs?

I am working on a font that is all built from bricks. In addition, I want the user to be able to generate a brick wall with a keyboard and {ss}. I know how to do it in FLS5.1 but the Glyphs naming system is new to me. Please see attached png and let me know the right way to do it in Glyphs?

You can use the same names as before.

So no need to use an .ss01 suffix on all?

I think Glyphs is mostly a stickler for specific suffixes when you’re wanting it to generate the opentype feature code automatically.

Thanks, Craig. I didn’t know how far to deviate.
