CorelDRAW Graphics Suite X5 :: Separating Colour Pages From Black Only?

The problem that has been with me for years is how to print a booklet as a single print job onto a digital printer that has say a colour spread on cover and centre pages... Coreldraw X5

Scenario: A3 12pp bookletI might receive a file in publisher or whatever but colour is generally on most/all pages but the client only wants  colour on say cover spread and centre spread pages. I convert this file to a PDF using distiller, then save it as an EPS file to import into Coreldraw. (The step to convert to eps seems very important as I have encountered font and spacing issues when importing PDF into Coreldraw - eps seems to over come this problem)Even saving the PDF in distiller as a Black only file, am still getting the colour click on the printer...

 is there any way to isolate say the cover pages and print as colour with other pages as black only I have tried saving eps files as black only but they still register as a colour print on the XeroxWould love to see an option to set properties of individual pages to colour or mono (does it exist?) At present, I have to print all the colour spreads and the black spreads and hand collate together! time comsuming to say the least!

surely there must be others out there with a similar problem? how do you overcome it?If I am designing I can easily ensure pages are black only but not when the arttwork is coming from so many different sources.
