CorelDRAW X5 :: Color Incrementing (Object Specific)

Any alternative way to increment an objects specific R, G or B color value? What I am trying to accomplish is to take a group of objects and increment the red, green or blue value by 5 without effecting the other values.

This has to be an increment on all existing values of each individual object. So if 3 objects have 3 different RGB's but I want to increase the RED on all of them by 5.

EXAMPLE
Object 1 : R-35 G-35 B-35
Changed to R-40 G-35 B-35

Object 2 : R-55 G-100 B-150
Changed to R-60 G-100 B-150

ETC....

I know this sounds specific but I am trying to create an RGB table the easiest way possible. In this example I`m referring to RGB but it could be for CMYK as well.
