We need the ability to set a given ecom B2B user as being an administrator on more than one customer account. This scenario is useful for people who are independent accountants/bookkeeprs and who represent multiple customers who buy from a given retail business. It would require an additional screen after login to select which account they want to work with, if upon logging in it is found that >1 D365 account is tied to them as admin. When they require to switch accounts, they could either log out and back again (not the best experience) or have a switcher in the ecom site to change between the ones they are assigned to.
