A little help - Routing internal, and setting default c-point

Hello all - two part question in routing.

1. If I uncheck the save route externally in my options (to keep it internal to the assembly) when I attempt to start a new route it asks me for a template, but the pop up is balnk??

2. When using "start at point" the default end length adjusment is alway 10mm - where on earth do I go to change that setting to zero?
