There is such a thing or at least i recall seeing references to it a couple of years ago on another uk forum but havent seen anything on it since. I have one from that seller and posted some pics of it in my album, also of the Zebrina but the pics i took of that are dire.
The pups i have of a dwarf cavandish and this cavandish red seem to have identical leaf structures, the only apparent difference being the stem colour.
I thought at first it may be one of these (Rubra) but it doesnt appear to be.
