I usually specify the PCB layer stack as you would a typical FR4 but then in accompanying documentation (detailed drawings) specify in the notes the the PCB as Xmm Aluminium Clad along with any other details.

the aluminum plate is not really part of the stack up, at least I’m not aware of anyone who makes PCBs with two different metals. As you yourself have noted, it’s a base plate, not really a “layer”. As scope probe points out, just make it part of the fabrication drawing.
