Line art help

So I had 2 questions about line art

  1. Is there a way to tell the modifier not to draw grease pencil on certain edges of a model? I know marking an edge sharp draws a line, but is there a way to do the opposite of that?

  2. Is there a way to almost lower the detail of a line art modifier? Ex.


Notice those dashes? is there a way to make it so that those lines will connect with eachother? (I know I could manually mark em sharp but I was just wondering if there is a setting for this issue)

Thanks in advance
