Questions before installing the plugin

I am interested in purchasing the premium add-on, I have two questions:

1. I want to create a selection option from among several options, and then use for repeated selection what the customer chooses.
   For example – a customer chooses 3 colors from several choices
   And then he has to choose one color for the closet doors, from the colors he chose.
   Is it possible? And if so, how do you do it?
2. Is it possible to create a dynamic pricing formula based on a dynamic field of the product? For example – a customer chooses a handle that costs $20, and the product has a field with the number 4, the pricing should be $80. Is it possible? If so how do you do it?
   Thanks
