[Feature Request] Disable an installation without uninstalling

Hi Unity Hub team!

I'd like to be able to disable an installation, but keep it on the hard drive and re-enable it when needed.

My use case is: I'm using 2018.2.8f1 but in our version control ProjectVersion.txt is some older version. Sometimes I'd click to open the project (forgetting to open it via "..." icon) and it'd open in the older Unity version from ProjectVersion.txt that I have installed, and start reimporting textures, whereas I'd preferred to open it with 2018.2.8f1, which is also set as "Preferred".

I like the Hub and would like to keep using it, instead of using the workaround which is to make a shortcut to 2018.2.8f1 directly.

 

open it with 2018.2.8, make a dummy modification and save the scene if needed.
it should set ProjectVersion.txt to 2018.2.8.
then either commit the file or keep it around modified in your working copy.

ideally you should make a separate branch for 2018.2.8 until you are ready to merge (then clone or git worktree to a separate folder to avoid conflicting Library/)
