Possibility of Signing Multiple Documents Simultaneously

I am currently working with 15 checklist documents that I need to sign. Each document is based on the same template, which I personalize with individual contractor details. Every document requires only one signature—mine—and the signature field is located in the same position across all files.

Additionally, each signed checklist must be saved individually, as they are separate agreements.

Is there a way to sign all these documents simultaneously or in bulk, rather than opening and signing each one manually?

Any advice or recommended workflow to streamline this process would be greatly appreciated.
