Ahh, so you are requesting a widget group that can be copied/pasted, I guess, this can be implemented as a widget library thing? (Pretty sure this is a huge project in itself, maybe can be a importable module, so as to not bloat vanilla decker) A work-around I suggest for now is shift-clicking all components of the desired group/elements and then pasting them elsewhere,btw can you provide more context as by canvas do you mean the workspace area of decker or do you mean the canvas widgets in particular?
