How to select all Objects of a Specific Color Only?

Can CorelDraw X4 select a specific color only?  Lets say I have a complex graphic with more than 50 or more colors and thousands of objects all on one layer, for example, is there a way to select one color, like Pantone 175C, but select all of the same objects that are Pantone 175C, and group them to change them all to a different color, like Pantone 478C. 

Any hints, this is easily done in Gerber software.  Thanks~~Mahogan
