Single order display on multiple accounts

This may seem a bit out of the norm however my bosses are wanting this done and I do not know where else to go. So our business model is b2b and not b2c. I know that WC is for b2c and does not support multiple customers under a single account, however I do not need anything crazy, I am merely creating a custom Account Number field that will be on the user accounts as well as on WooCommerce orders. That way if one of our customers has any of there 10 users order something, all those orders are displayed across all accounts. So my question is this, how do I change the orders shown on the My Account page to display from a custom Acc_nbr field in the database instead of displaying orders based off of customer_ID or curent_user_id?
