Capture user mouse coordinates for use in function

I would like to write a two part function -

I would like to place on the form a series of fields that the user selects via an added menu item (common fields that are often used on similar forms).

However, right now I am just placing the fields starting at the top right corner of the current page and incrementing them down and over as necessary.

I would really like to give the user some input into where at least I start putting the fields. I would like to capture the coordinates of the first mouse click after they select the option to use as my starting rect points.

Is this possible?
Is anything like this possible?

Obviously Acrobat itself is doing that when I draw a new field, but how can I leverage that same functionality...?

any help would be greatly appreciated.

PS - this is a folder level script and can be made a trusted function if necessary.

Thanks!
