Support multiple formats on the Add Waypoint dialog

Currently, the Add Waypoint dialog only supports entering waypoints in the currently selected format.  I would like the ability to select the format to be used in that dialogue box. (E.g decimal degrees, degrees-minutes, degrees-minutes-seconds, UTM, MGRS).

Currently, if I have coordinates for a destination, I have to go in to system settings and change the application coordinate system to match the format that I need to enter, then use the Add Waypoint dialog to add the waypoint, then go back to system settings to change back to my preferred system.

Thanks
