Multi-resolution icon

If I add an image bric, I can add images for different resolutions (1x, 2x, 3x). How do I do this for the logo image on a navigation bloc?


(Multi-resolution image below - all good)

(Logo image below but can’t see how to add multi-resolutions?)

I’m not sure that you can directly - easy workaround is to supply an image source at 2x the required resolution.
