Possible to save a texture in a save game?

I’ve made an in-game level editor that will allow players to create and share custom levels, as well as being an easy way for me to design the levels that will be packed in with my game. I’d like each level created with the level editor to have a screenshot that will show up in the menu UI when choosing which level to play. I’ve got the screenshot created with no difficulties by using a scene capture cam and converting it to a texture2d, however I can’t seem to find a way to save the resultant texture as a variable in my savegame, merely a reference to it, which is obviously overwritten any time a new screenshot is taken. I could take a screenshot and save it as a png file, but it seems like a hassle to deal with the paths if there’s a simpler way. Any suggestions?
