Inserting username into a pdf form field

[Pookiemeister]

I have a pre-existing pdf order form which I added form fields to it which people can add the quantity next to the desired item. In order to get access to the form they would have to login into windows to open the pdf. On the top of the sheet, there are three form fields, the first is for the user to type in their name, the second is the area/department of the warehouse they work in, the third is for the date. I am currently using pdf element as my pdf editor. They have the option to format the date form field to include the current date, which I using. As the title states is there a way to enter the Employee name based on their username. I know in excel you can use this code to retrieve their username.

Application.UserName

Is there a way to achieve this for a pdf? Thank You.
