Can SignServer-CE PDF Signer sign a specific field (signature placeholder form field)?

SignServer-CE PDF Signer works great for me, with signing pdfs via API.
I can sign with invisible signatures or visibile signatures and, for the visibile ones choose where and how to display them.

Some documents though, have specific places where the document needs to be signed.
If I sign such documents with SignServer, it adds another signature instead of somehow tying it to the existing signature formfield placeholder.

When inspecting the document's signature pannel after signing it with SignServer, I can see both the signature applied by SignServer and the "Unsigned Signature Field" that I would have had loved to be signed by SignServer.

Can SignServer-CE, when signing, tie the signature to the curently "unsigned signature field"?
I

can't seem to find any parameters for that.

Got it, for reference if anybody else needs it, this can be controlled by the VISIBLE_SIGNATURE_NAME in the worker request metadata properties.
