Duplicate Timeshift backups name

So I have 3 different linux distros using the same partition to store backups using timeshift. 1. Arch linux 2. Arch linux 3. Ubuntu 20.04 I installed one of the arch linux a few days ago, and now after doing all the base setup to get me started, I finally setup the timeshift in the end. But the problem is that both the arch linux installations have the same name when opening the timeshift app. See the image. See, both the arch installations have the same entry under System. So, I just want a way to differentiate between the two installations of arch linux. So, what options have I got. All are rsync backups, if that makes any difference.
