BR Render nodes pick wrong GPU, can't over ride

Fusion 16b1 render nodes pick wrong, least capable GPU in multi GPU machine. specifically I use my i7 MBP 2016 to render sometimes. Its got a intel built in and a quite decent AMD 460 4gb VRAM GPU. the render node defaults to the crappy intel GPU first and there is no way to force it to use the AMD. At the very least render nodes should pick the MOST capable GPU, not the least. Ideally a user over ride would be better. This probably also affects BMD eGPU users as well.
