Can I add a handle or anchor point to a room outline?

[namcam743]

I'm new to Sweet Home 3D. I looked around in the forum and even tried Googling, but cannot find any info on this question. I've drawn a room and added walls, but have also moved a wall, and now want to adjust the room size to fit. I know I can delete the room and redraw it, but thought there must be a way to simply add anchor points or handles (not sure what those are called) so that the room can be stretched to fit the new wall outline. Any help (even to say it cannot be done) would be appreciated.

There's no way to attach a room to its wall in the current version.
But if you don't want to redraw a room after moving some of the walls surrounding it, notice that there's some kind of magnetism at each wall corner that helps you to drag and drop precisely the room corner you want to adjust.
