How can I remove an install from the Hub without uninstalling it? My install got overwritten.

I used Unity Hub 2.2.2 to install Unity 2019.3.0.f5, worked just fine. Later on I needed to install Unity 2019.2.16f1, which wasn't possible with the hub since it's not the latest 2019.2 so I did it manually, and didn't pay attention to where it was installing - it uninstalled 2019.3 and then installed 2019.2.16 in the same folder.

So now, Unity Hub thinks I have 2019.3, and that install points at 2019.2. It also has a separate 2019.2.16f1 in the list pointing at the same folder, so I just need to remove 2019.3 from the list so it will let me re-add it. But as far as I can tell the only option is to Uninstall 2019.3, which would actually uninstall 2019.2 which I don't want to do.

I have two projects which need the two versions of Unity. Any ideas?
