Default [Q] Change apps on Samsung desk home screen?

Hello,

I have a Galaxy S4 running 4.4.2 and a Samsung smart dock. Recently I have been playing around with the two attached to a tv and accompanied by a wireless keyboard/mouse. I am interested in using the Samsung Desk Home Screen instead of my normal "desktop". I would like to change a few of the apps docked on the screen for more useful ones. Is this possible?

Thanks,

JL
