Windows – RDP Dual Monitors treated as one

The Windows Remote Desktop Connection tool allows use of dual monitors by leveraging the /span option. The problem with that option is that it treates the remote dual monitors as one large desktop instead of two distinct desktops for each of the left and right monitors. This is a pain because maximizing a Window or application will span both monitors and consume the entire screen unless manually stretching it into position of one monitor. Another problem is that dialog boxes that are suppose to pop up in the middle of the desktop now are split dead-evenly in half by the two monitors. Is there another option that I could be using so taht the remote monitors map exactly to my monitors instead of one giant spanned desktop?
