Modifying REST requests

Hi 

I am trying to test a REST web service that has one GET operation but this operation can have a different Resource path and take different query parameters.

It returns details of office locations and can be used by either specifying the postcode or giving geoSpatial values (longitude and latitude).

The resource path can either be /xxxx/v2/locations/<postcode inserted in here>

or /xxxx/v2/spatial and the longitude and latitude are specified as query parameters.

I want to create 2 different requests structured as detailed above so I created multiple copies of the Request in Ready API, but I find that if I change the Resource or add or delete query parameters in one request it applies these changes to all requests.

How do I create seperate GET requests structured differently as specified above.

Thanks.
