Placement and appearance digital signature

I have a couple of questions about the placement and appearance of the digital signature.

First the placement:

Is it technically possible to place the digital signature after Word-fields when you convert Word to PDF/A? For example the { DOCPROPERTY "Name" }? Where the name is a custom field.

Appearance:

What I am trying to achieve is to get a digital signature appearance just like the one on an analog paper. Just the name, date and a picture of the analog signature (created by tablet, scan or mouse). Is it possible to get rid of the following:

Question/check mark?

The text "Digitally signed by"?

The line with the attributes from the certificate?

Thanks in advance!
