render pack shot with shadow and pack shot with shadow + background in one render

[fraggle]

Hello,
I have to render several object in pack shot with:
- white background + shadow on ground plane, no ground reflection on the product
- the same scene with mapped ground plane background + shadow and reflection of the ground plane on the product.

I know how to handle both with 2 render but I'm wondering if the 2 can be done in only 1 render to save time!

Thanks

I don't think this is possible to do in one render pass. It would mean tweaking some settings that will require a second render.
