Creative ways to post rent price when utilities are included.

I'm wondering if there is a creative way to list my rent price. Currently the utility prices are included in the rent because I don't have split meters. The problem with this is that it drives up the cost of the rent – even though in reality is is less total costs per month since the utilities are included. I think I am not showing up to the potential tenants that are looking in the same price range as my listing. Is there some way that I can list the rent price differently and still be legal? Currently the cost of rent is $1625 including utilities. Could I advertise it as $1400 with a set $225 utility fee? Or is this dangerous territory in terms of legalities?
