is it possible to load the content dynamically to the sheet?

[cwikio]

I dont want to use the component in every other component. I would like to have it more like a useContext around the app, where I just load the content from which ever component I want. is that possible?
Also, if not, how is the zIndex governed in sheet? ie. if I trigger it from a sub-sub-component, how do I assure it is at the top level above anything else?
