A better way to handle multiple businesses within a single Ontraport account

I would like to make a request to have a more dynamic way to handle multiple businesses. Right now we are able to handle multiple businesses using the "Contact Owner" field which works ok, except when we have customers that purchase products from both companies.

How can we dynamically display the correct company info in the footer if we can only set a single contact owner?

I am not sure how this could be accomplished, but wanted to put in a request.

Thank you!
