Moving layout between windows

Hi Cadence,

I have two windows related to same library but different cell views, Sometimes I Move layout structures between the windows through GUI mode.

I Need a script which will Move structures from "Layout A" to "Layout B" and the script should not delete existing "layout B" instead it should append to "Layout B" .

(This is optional) One more add on I require is that, I should do window selection of structures in "Layout A".

Thanks & Regards,
