Use of Flow App to recognize non B2B customers to charge shipping on catalog of items?

Hello,

I’ve set up my catalog of items for B2B companies & assigned my customers as a company to be part of the B2B profile.

I’ve also set this same catalog of items up to receive free shipping for Ontario customers in my settings.

Is there a way using the Flow App to have it recognize the customer not being on the B2B company list to charge shipping if in Ontario?

Or some other way to complete this?

I have customers who do not qualify for the discounted B2B pricing & free shipping in the same province.

Thanks in advance!
