Importing mixed Colour and B&W Images?

Hi folks,
As a current Lightroom (and previously Aperture until it kept crashing and having to rebuild libraries), I have recently been advised of this application so decided to give it a try. Currently using a Canon EOS 5D I have taken a load of photos where some I have set as Black and White. In Lightroom it correctly displays them in either Colour or B&W as I have taken them.
With Capture one they all display in Colour and I don't want to have to go through 300 Photos either in my Camera or use another package to see the B&W images and then have to select them manually or in groups to change to B&W.
Is there any way in Capture One I can have them display what I have taken in the way I have taken them?

I copy all my photos from the CF card to a named folder on a hard drive then import the Capture One Catalogue leaving the originals in place.

Thanks!
