Apple Maps: Renaming Favorires or Marked Locations

There must be some really obvious trick which has escaped me.

If I favorite a marked location on MacOS Maps, or on iOS Maps, I can’t see how I can give it a custom name.

Tapping or clicking on Info doesn’t seem to help, and I can’t see any other method.

I have tried the technique of selecting favorites from the search bar

(in MacOS), selecting edit and trying, but the text remains uneditable.

I would even consider a third party app if there is one.

I am using MacOS Mojave, and iOS 12.
