create a button for draft documents

Hi all!

I know the only way to generate a draft document is to go to File -> Save as draft document. But is not very user friendly...

So I want to create a button in sales documents for drafts.

When the user clicks the button the document is added as draft.

Is it possible?

Or is there a better solution?

Thanks in advance for every help!

Kindest regards,
