The best way to draw centerline marks

I was hoping if some one can point me to best way to draw center lines given a view ? I know i can select edges that makes the top/bottom  left/right and then do an insetcenterline3 type of command.

What I am was wondering is there something available at the  view/component level ? Pretty much all my parts are rectangular so i should be simpler- I  am assuming.
