Is it possible to change work area size?

hi,
i’m new to this list.
i am working on a project, and i’ve already done a whole lot of work when i realized what i have been doing won’t fit on the work area. i’m doing a scrolling thing and i’m building it in the main stage, but i’ve used up all the grey space on the bottom. is there any way to move the whole stage and everything in it up so i have more room on the bottom for my scrolling stuff?
i’m not sure what to do at this point. any help appreciated.
thanks.
