Add Customer ID

We are shipping for other customers, and we need to invoice each customer separately.

– It is not possible to create a sub-account for a third party in the Bpost plugin.
Our account number is always used because the contract is linked to our account number.
– It is possible to create different users in the User Management of Bpost Shipping Manager, but not to link them to the plugin, so you have to make the labels (not using your plugin) manually (or import a csv file) if you want to make different labels for different users : not practical.

On the other hand, what could solve the problem quite easily is to add a drop-down list field in the plugin:

Username: includes the main user + all our registered users in BpostUser Management.

And on each site, we select a different user, which links the label to the right user and allows segmented billing.

Is it possible to develop this?
This will help Bpost expand their customers to all logisticians who do third party invoicing.

Thanks
