I am creating a lot of dvds with multiple chapters (up to 20 per Scene Selection Menu)

It is easy for me to create the chapters with the M key but the default is #:Scene/Chapter

I know I can change it by clicking on the Scene and editing it but it makes a lot of work for me.

Is there a way to set the name default for this? I would like it to read #: Horse as in 1. horse; 2. horse, etc

I sure hope there is an easier way than having to change them all manually
