Changing sub-report type (inline or banded)

Hi,

Just starting to get into using the report designer a bit more and have a query regarding changing the sub-report types as I have created a few reports that I may have chosen the wrong type when inserting some of the sub-reports.

Is it possible to change the type from inline to banded and vice versa? If so how?

Also is there anyway to get to the source of the report without having to unzip the prpt and zip it backup after?

Thankful for any help
