I've just bought Website X5 Professional and one thing I would really like to see is the possibilities to also add a price difference to the Sub-options,
and maybe the possibility to add more options/sub-options.

I run a print service and my products do have many options.

The best would be to be able to make a ordeform that automatically calculates the price or something similar to this:
