Working from two states

I’m a remote employee based in one state, but I often travel to another state and work from there because my fiance is there. I try to go there for half the month if possible – I have kids in the state where I live and spend the other half of the month with them.
We have a new policy which limits the amount of time you can spend working in another location every year. I wanted to talk to my manager about potentially having dual residence so that I’m not violating any policy. Has anyone ever done that successfully with an employer?
