Unmelting snow/ice items for building

I think there should be a setting in game for unmelting snow/ice, there are several things snow and ice could be used for in building but for an example, regular snow could be stacked with regular snow blocks on top of an invisible blocks like structure voids to make clouds but people can't do that if the snow melts or something like an ice sculpture that's built outside of a snowy biome could melt if it's not blue ice. Showing these small examples, there should be an in game setting to turn off snow/ice melting outside of a cold biome, it could help people add the snow or ice they need to their build without it melting on them within a minute.
