Is User defined changes possible?

I have installed to our server win2003 MSSQL Reporting service and client version on my pc together with visul studio. Everyting works well.

My questions are several.

1. When we use subscription by email. RS sends report by email as we selected.But i couldnt find the way to change the email layout.



2. Is it possible to change web layout. I couldnt find the cs source codes of the report server.

3. I want to remove refresh button from the users view. Is there any configuration for the layout where we can change it?
