See the method addtag_withtag of Tkinter.Canvas .
So instead of passing tag1, tag2, etc. to find_withtag, you can
use addtag_withtag to add a new, unique tag to the ones which have tag1,
then to those which have tag2, etc. then pass this new tag to
ps. you don't have to create a new tag for each item. The when creating
an item with Tkinter.Canvas.create_* methods, the returned value is a
tag which is unique, only that item has it.
