Is there any way to make hotspots(markers) grab the image from their category by default (we already have that), but include another image(marker) inside that hotspot tab to override the one by default?

Let's say that we have the category restaurants (all the markers inside that category will get the restaurant marker image). But I have one chinese restaurant inside that category that I wanna make it looks different. Then I can upload another marker image to only that hotspots to show a different marker on the map.
