Are there ANY Insurance companies that can write a policy (HO, Auto & UMB) for properties in multiple states?

I asked this q a few years ago - and got responses that there WERE - but since then - I have had NO LUCK in actually identifying a company that could cover our insuance for properties in multiple states for homeowners, auto, liability (and possible flood insurance). I am tired of mult policies, mult bills, and know that consolidating to one provider SHOULD be cheaper as their risk is spread over a large geographical area. To date - no luck - but an open to solving this quest!
