To answer your curiosity, yes you can. The RFM usually specifies an ITT limit for starting prior to fuel ignition. If the engine is still hot after a recent shutdown, and the ambient is hot, a starter cycle limitation might not get you the pre-fuel ignition ITT temp drop you need. If there is an operational reason for hot refueling, such as being in hostile territory (whether in a military sense, or sitting on the top of a remote mountain where they can't send the cavalry to get you going if you break down, or whatever) then it's sensible to hot refuel.
