I dont know if this is the best way to do it, it works thou. I may play around with other ways to do this - particularly to have it adjust continuously instead of just at the task activation. (recalling, i'm not sure if it continuously checks those actions, i dont think it does thou)

And for anyone interested how I have tasker setup:
