How to mass update a custom Business Object?

Hello community,

do you know if it is possible to mass update a custom Business Object?

We've created the following BO:

At the moment we are just able to create entry by entry, which leads to huge effort to maintain these Business Objects.

Do you have any idea how to mass update these BOs? Or if is there any workaround for this?

Thank you in advance.

Best regards,

João
