Create dimensions in Creo 3 Drawing

Hi to all,

when i try to create a dimensions in Creo3 (ex. space between two lines) i have to:

1) Click on first line

2) Control+Click on second line

3) Middle botton click

4) Middle botton click if i don't want double value.

Can i avoid 4) step with a config.pro option?

Thank you.

Picture after 3) step.
