Spacing with devices?

Hi,
I have one collcetion “Global”, where all the brand colors are stored and of course the spacing.
Spacing is just like this:

BUT we also got a collection called “Devices”, for web, tablet and phone.
And here we need the spacing aswell, since e.g. the paddings change from web to phone.

My question is, is this the right way and how do I create the naming in the “Devices” collcetion for the spacing, of course the values are alis tokens from the “Global” collection.

Thanks
