DocuSign Widget: Does it allow to connect to a custom document?

I am curious if the DocuSign Widget allows you to create a signing order?  Or how can a signing order be integrated into a Jotform?

Unfortunately, the widget does not allow to connect to a custom PDF document, it's however possible to create a custom PDF document on your form, you can also import PDF fillable forms. Kindly check this guide for more details: https://www.jotform.com/products/pdf-editor/

I hope this helps.
