APP Assign Sold-To Parties

Hi Experts,

We are working with Sales Scheduling Agreements and the "Assign Sold-to Parties" APP.

Customers are asking for the possibility of massively upload sold to party assignments in the system.

Is there a way to do that?

Thank you very much in advance for your comments,

PD: it would be great if the following ODATA API could use POST and PATCH services.
