Shipstation already allows a user to add multiple carrier accounts to one Shipstation account - Article Link. And Shipstation also already allows a user to add multiple free Stamps.com accounts to one Shipstation account.
So why not also allow a user to have multiple UPS by Shipstation accounts? I would like to add different credit cards to the UPS by Shipstation balance, but this feature is currently not available. In speaking with a Shipstation rep in chat, it sounds like the only expense to Shipstation is paying for the additional Stamps.com monthly subscriptions and if they already do that, what's the issue with this additional option?
