Niagara localised resolution

Hope this is an ok question. I’m working on my research and dev project for my dissertation, and am studying real-time water interactions.
I was wondering if it was possible to have a low res pool of water, and an actor with a bounding/collision box attached to their feet. I would in theory like the water inside this box to be high res and have more particles to create more dynamic splashes, whilst keeping the rest of the water at a low res to reduce render time. If this is possible, could it be accomplished via blueprints or would I have to write my own function in c++?
