Templating DCT save functionality.

System

Hi.

i have a scenario in DCT.
i want that when i save the DCR, it by default takes the value in one of the specified field from the DCT(datacapture.cfg.)

for example. one field name is contry. so when user click on the save button. it direct takes the value from the contry field in save window.

Is their any method or code. plz suggest.
