How to add a specific shortcut for inserting signature fields in Adobe Acrobat Pro?

Hi,
I'm using Adobe Acrobat Pro (latest version) and I would like to add a shortcut to the Quick Tools bar for inserting specific form fields, such as a signature field. Previously, I had this functionality configured, but now I can only add the "Edit Form" tool to the bar, which requires me to open it and manually select the signature field afterward.

I've reviewed the customization options, but I can't find a way to directly add the tool for inserting a signature field (or any other specific field) without going through "Edit Form" first.

Does anyone know if this is possible in the current version or if the method has changed? Any help would be greatly appreciated.

Thank you in advance!
