PDF Save Button that auto fills date and set default save location on desktop

Hello, I designed a editable form pdf for a client who will be using Acrobat Reader on a Windows computer. I have the buttons: CLEAR, PRINT, EMAIL, SAVE in the document.

I am not familiar with scripting.

I am trying to develop a javascript that works within the SAVE button that on button up action will bring up a save as window with a preset folder location of the user's desktop with name field auto populating with a set value followed by a name field along with a date field from the document.

Is this possible?

Here's an example:

Form name: Invoice

Name field in form: "BOB"

Date field in form: "02-15-15"

Save to (window will go directly to the folder):

Users desktop folder named "Invoice"
with name "InvoiceBOB-02-15-15.pdf"

at this point all the user has to do is click save in that window.

Thank you community, I hope was clear enough in explaining my situation.

I appreciate the help.

By the way, I'm designing on a MAC, users of the form will be on PC if that matters.
