Please add support for the USPS LabelBroker feature - customer returns by scanning a QR Code

I use ShipStation for a rental service and automatically include USPS return labels. Invariably I have to email customers return labels from ShipStation which isn't a problem, except these days many customers don't have a printer.

For customers the norm is to be able to go to UPS or USPS and scan a QR Code to ship an item. Poshmark does this with USPS LabelBroker Integration, and customers are used to going to UPS for Amazon returns and scanning a code from their phone.

I'd like to request ShipStation integrates with USPS LabelBroker so I can email my customers a QR code, so they can package up my product, take it to USPS, have USPS scan the QR code and print out the shipping label. 

Thank you.
