Different settings for chunk.section.depth for different parts

["Elias Gerber" <eg@viscomvisual.com>]

Hello everyone.

Is it possible to define different values for the parameter
'chunk.section.depth' in one book?
In my case my book has two parts, in the first part I would prefer a
chunk.section.depth value of 1, while for the second part a value of 2 would
produce nicer output.

Thanks for any hints
