I decided the best way to keep track of a catalogue of published photographs without disturbing their original hierarchy was to drag aliases across to a separate location.

However, many use-cases require the original; they can't cope with having the alias itself dropped to, eg a web site, or Photos.app

Right click - Show Original insists on showing it inside the same window container, so going back to the alias folder loses its place, the selection is gone. In a large folder, this really tests your memory as to where you were up to.

Is there any way to force it to open in a new window, similar to Cmd/double-clicking a folder, thus keeping your place in the folder of aliases?

Currently on High Sierra 10.13.4

Update:
After the two answers so far I have moved the goalposts slightly. I need multiple selections & tabs - the existing answers; one has multi-select capability, the other gives me tabs, which I've realised is the way to go.
