You sure can.
You need to put the callsign of the repeater you are linking to in the "UR Callsign" field. Make sure you have the module of the DSTAR repeater in the 7th position and "L" in the 8th position.
In the Repeater 1" field, you need the callsign and module of the repeater you are using in the 8th position and the callsign and "G" in the 8th position of the "Repeater 2" field.
Check out DSTAR Info.org. They have a great calculator tool that will tell you exactly what to put in which field.
