mapping of lines in sketch

Hi,

Is there a way I can map a line to a new line inside sketch.

For examble, I have few lines in sketch 1, which i had used for constraints and dimensions in skectch 2.

now I have decided not to have dimensional and constraint reference to external sketch. So i'm creating lines in same position and making it collinear with the sketch 1. But there are so many dimensions and constraints also need to be mapped now.

If NX has a functionallity of line mapping kind, I can say which line is for which of the old line, and all the relevant constraints and dimensions would be mapped here.

Is there any of such kind options ?

or any altrnate approach "?

thanks !
