Archivelink Workflow: Add 1 Document to x Business Objects

Hello Experts,

I have to set up an Archivelink Workflow, which leads a document through the system due to several approval steps, in the end the document will be linked to an existing business object (e. g. kna1 customer master). The problem is that there can be documents, which must be added to more than just one business objects but standard SAP Task 30001141 allows only 1 business object.

Is there a possibility to handle this with standard SAP-Tasks?

Thanks in advance! for a short feedback.
