Custom linestyles ORD - drop annotation scale

I'm newer to ORD and have been googling for a resolution with no results.


I have a custom linestyle of dashed pavement striping, 10' dash w/30' gap.  is there a way to drop the annotation scale for those lines so they wont scale according to drawing scale and stay true size?  i need those to stay true 10'/30' regardless of drawing scale.  It would only need to be applied to those dashed lines, other custom linestyles will still need to stay active with drawing scale changes.  I just haven't found a solution yet and would appreciate and feedback for remedy.
