Creating a Custom Dynamic Stamp in Mac

Good afternoon, 

I am trying to make a custom stamp that enters the date automatically. I was searching prior discussion posts and it would lead me to find the stamps in the file sequence below. 

Library/Application Support/Adobe/Acrobat/DC/Stamps

Only issue is that there is no stamps location in my file system, so where would i go to modify a stamp to be dynamic? I have the latest MB Pro with M4 chip. 

A seperate issue too is that, I woudn't mind inputting the name, date and signature each time, but the stamp is placed in front of any data. Is there anyway to set the text to be sent to the front such as in word?
