Creating a custom report

Subject: Creating a custom report
Description: I am looking to create a report from CM ZMF V8.1.0, with the following information:

Package names (for a given time range)

List of SRC components in each package

Work release #


Lines changed in each SRC/ Total lines of code in that SRC

There are some reports close, but nothing with SOURCE LINES CHANGED/TOTAL SOURCE LINES.
I can obtain this info by using package lists, and further use of 'VC' and compares, but would like a report or XML that I could run more readily in batch or online from TSO.

Does anyone have a similar report or advice?
