Having a way to implicitly add a serial no. Makes it easier to find the data. Also if we can add a scribble pad to save notes.

I have a form which takes in patient data and saves it in Xcel sheets. I have automated it to have notifications when someone submits. If there was a way to have a unique ID which can be used to traverse through the data. Also we have a signature field, if we could have a scribble pad to write down information would be great.
