Export Scene View's water heightfield?

Is there a plan to create an export node for the water heightfield that is generated by the scene view node? This would be really useful for exporting complex water surfaces to other programs. I can see the heightfield with the scene view node, but I can’t save it! Can the logic that shapes the water input to conform to the terrain be recreated with other nodes in the meantime? What is the logic that the scene view does to create that heightfield? Thanks!
