It'd be great to have the possibility to copy-paste a mesh from a scene (sceneA.max) to another one (sceneB.max) with a shortcut.
Like CTRL+C & CTRL+V on gizmo in nuke.
example: in SceneA.max, you select a sphere, you hit the copy shortcut, you go in your second max window, you hit the paste shortcut and your sphere and its modifier stack are merged into the 2nd max scene at the same position, like the standard merge tool.
