Are relative paths to “$” possible?

I like to buy your shortcode plugin, but i have a special need:
I like to give every user some individual directories relative to the “$” path. Is something like this possible for a user with name “test”:
path=”$/download/” -> does it expand to: “wp-content/uploads/file-manager-advanced/users/test/downloads/” ?
and
path=”$/uploads/” -> does it expand to: “wp-content/uploads/file-manager-advanced/users/test/uploads/” ?

Your documation states:
$ – Will generate logged in users personal folder of their username (unique) under location “wp-content/uploads/file-manager-advanced/users”, use path=”$” in shortcode.
