Optimize "Draw" Signature Settings

The “Draw” signature is not the best at representing my brand at all, I wish there's a feature where I can change the settings of the signature drawing pen. ex: Pen size, pen pressure, maybe pen color.

It should also be optimized for Stylus, and Wacom Tablet for more accurate pen writing.

Lastly, Attaching a File of  my signature should also be an option for the people that has specific branding of signature.

Thank you Programmers.
