I need to create page numbers in the format 1-0.1, 2-0.2, etc. Here the number before the dash is the chapter number and the part after the dash is relevant to that particular chapter. I have been able to figure out how I can manage the 1.01, 1.11, 1.22... etc , but how can I change the number before the dash i.e. make it 2.01, 2.11 etc.

Any help will be deeply appreciated.
