my system has /var on a seperate device. Is there some way to add it to the snapshot?

as the title says, my system has /var on a seperate device as I wanted to reduce writes on the SSD. I think it should be included in a snapshot. Is it possible to add it? I do not see a way to do it in the settings. thank you
