SSRS Design Parameter Area for a report only

Hi, I need help please.
I want to change the design of the Parameter Area for one report only. I would like to set the height and background color but only for my report. Reason being I'm opening the report within another application and what it to keep the standards of the application.
I also do not want to affect the design of current SSRS report which should remain default.
It is possible to change the parameter area for a specific report only.
Please Help.
Regards
