You can do it now with worksheets or details.
They can be placed as an irregular shape or they can be edited to any shape (so long as the 'Marker Range' button in on-screen options is turned on).
You can set them to 'Copy construction elements only' which means they won't copy the plan 2D annotation at all.
Or you can use layers to turn on/off the annotation.
They are not a 100% live view (which is why I personally don't use them) but you can open them, right mouse click and 'Rebuild from source view'.
So you can have your cropped room view and then annotate around it in the actual worksheet or detail at whatever scale you want.
