Case PDF missing content - case_update_text

Hey guys,
recently I wanna print the content of a case.
while the update part didn’t function that:

the description stores in cases.description
but the update text stores in aop_case_updates.description
while the id of case relates to case_id of aop_case_updates

how do I
1)modify the dropdown list of pdf templates
or 2)modify the parser
to print out the case updates when I ask it to print a case

Have you looked into the Reports module? Actually I don’t know if it handles Case Updates, but it might…
