shortcut "digital signer"

Hello

I use adobe reader DC

I need to electronically sign PDF files.

However, I have a large number of documents to electronically sign each time (per 30/40 pack) and so it is quite cumbersome to manage.

I would have liked to facilitate the task, 

- Either by adding a keyboard shortcut to go : ("OTHER TOOLS" >  "CERTIFICATES" >  "digital signer")

- Either by another means

Do you have an idea or solution?

Thank you

Best regards
