Book has Module 01 , Module 02 with nested chapters but with the rundown page numbers. Any help, please ?

[exploreg]

My book has a structure with Modules and rundown pages like Module 01 Page 3 to Module 01 Page 20 and then Module 02 Page 21 to Module 02 Page 58 etc. and it also has roman numbers in the beginning for Table of contents. I tried the scripts that you provided and also tried modify to get to this structure but no success. Could you help me to provide a script to support the above structure ?
