rgb led circuit problems-please help

Hi all, I would like to purchase this rgb led driver but I have one question before I do. As noted in the picture below, the power supply is connected directly into the RGB controller which is then dispersed throuth the R, G, and B channels respectively. The power supply is then connected into three constant current modules that ultimately connects to the respective red, green and blue leds. My question to you is this, can I plug my initial power supply directly into ONE of the constant current modules and then connect it to the RGB controller. By doing so I will provide the whole system with a constant current supply and therefore save both space and money. For a complete look and understanding of my issue please look at the connection tutorial site. (especially page 3)
