Price Constraints in DOE

I am using Sawtooth Software SSI Web to create a Design of Experiment.
I want to know how can I add pricing constraints based on an Attribute.

For instance, amongst my attributes, I have Size Attribute and a Price_Size Attribute.

I want to add a constraint such that in a task, between two concepts, the 10ml sized concept is priced lower than the 20ml, 30ml, 40ml sized concept.

Is it within the scope of the software? If yes, can you kindly help me understand how I can proceed? Any reading material would be helpful.

Thanks.
