For cases where the main floor member is not a product ForteWEB sizes for, in many cases open web wood joists, it would be nice to able to model a "non-physical member" just to be able to use the load transfer to the carrying member. I'm a huge fan of linking members because if you do it right you really only need to change an area load input at the top of your load tree for a change to be made for the entire assembly. Having to re-calculate some vaguely specified point load a few months after stamping drawings due to some site change or design change just bogs down the workflow.
We usually include dead load of joist in our assembly, so the "non-physical member" wouldn't need to analyize anything, just calculate reactions for the purpose of transfering.
