Continue in line width while routing automatically

Hello guys,

I was trying to find out if Allegro can do this but without any success. I am  using version 16.6. I would like to know if Allegro can automatically continue in line width while router so I do not have to type line width every time. Example: I delete some Cline segments from line wide 12 mils. Then I delete some Cline segments from line with width 20 mils. Now I want to route the first line. But instead of typing the line width to Options window, I would like to click on the line and allegro automatically continue in the wide of this line. So back to example - if I would click on the line with width 12 mils allegro would continue routing with 12 mils line. Same for the 20 mils. Can this be set somewhere? It would ease my work significantly.

Thanks for any response.
