Unable to add arguments to cmake command

With older versions of QtCreator (3.6.1 and earlier), when running cmake (Run CMake), the CMake Wizard contains an Arguments: field where variable defines could be added (-DVariable=Value). QtCreator also remembered these (though a drop down arrow would have been nice to more easily recall these).

With 4.0.0 (beta1/rc1) and the new CMake changes, there appears to be no where to enter these arguments.

There should be an "Arguments:" field on the Projects page in the CMake section. The text entered here (it should remember different fields entered access with a drop down arrow) would be transferred to the cmake command line when ever cmake is run.
