Not sure what DAW you are targeting, but I simply open RB (then move the RB window to the right side of the screen)
Then Open the desired DAW, and position that on the left side of the screen.

Then drag the files from RB/PT to the DAW screen, and they just load as tracks, where I can then zero/flatten them there as desired. Most of the time they load centered/flat.

If not, at least it saves all the render to wav steps and the resulting un-needed files laying about.

Quick way to do this;
Open RB, make sure it is not 'maximized'.
Hold the Windows key on your keyboard and tap the right arrow key. RB should snap to the right half of the screen.

Then Open your Daw and use the Window key + left arrow to snap it to the left half of the screen.

Than drag the tracks from RB to the DAW.
Works a treat here.

Make your sound your own!
