Yes there is. The procedure for this is defined in Barry Broskowitz book. It boils down to exporting the information from your DCS remote to a file, changing the extension of the file and importing the file into the app. You'll want to reference pages 115 & 163 (1st edition) or page 119 (2nd edition).
I'd recommend getting a copy of the DCS WiFi Companion volume 2 from MTH: https://mthtrains.com/60-1411.
