How to send REST request with some parameters?

I have a REST request that has 3 parameters (colorId, typeId and name).  Only colorId is required. 

I would like to test with sending 2 parameters.  For example, colorId and name. 

When I created the URI for this REST web service, I included the 3 parameters.  In the test, there is no way to delete any of the parameters.  Cloning the URI and removing typeId parameter, removed this from the original URI. 

Is there a way to set REST request test to send 2 of the 3 parameters?
