GUIX Question: Is there a way to use the vertical scroll function inside GUIX ?

Trying to design bunch of buttons inside a 480*272 screen with the ability to scroll,

I am able to design right now by making the overall screen bigger and add some buttons outside the 480*272 and scroll in the target platform to view it.

But is there a way on GUIX to use the vertical scroll and design buttons with in the same 480*272 window space?
