Possible to use parameter named "Body" in HTTP request instead of the 'Body' property under Options?

I am trying to use a POST service call in the HTTP request activity. The problem that I am having is I need to use a parameter named “Body” in the Parameters collection and when I try to do that Studio yells because there is already a Body property in the Options section for the HTTP request activity. When I attach the body in the property as a string in the Options section I get a response saying “Body is required.” How can I work around this? Anyone else experience this issue?
