One fulfiller account that lets you intergrade and handle multiple client's ship station account .

As a decorator and fulfiller we work with multiple clients who give us access to their shipstation account via a staff account as they would like to use their preferred carrier account and manage their shipping cost.Howver , this means we have to toggle between 4 accounts ( and shipstation connect!) to fullfill everyday's order - which is super cumbersome . It would be nice if shipstation had a fullfiller freindly app that lets us intergrate with client shipstation account ,review orders on a daily basis and fullfill them using cistomer presets ad payment method .
