How can I configure Unity Hub to install things to my D: drive?

I installed Unity Hub 2.0.3 to my (large) D: drive, this has gone smoothly. Then from within Unity Hub I have installed Unity 2019.1.10f1. This has been installed to my (small) C: drive. How can I install versions of Unity on my D: drive?

You can edit the Editors Folder Location by clicking on the gear on the top-right corner of the Unity hub. It may not be present if you have an “old” version of the Hub though.
