Dear Jim,

thanks a lot.
I really tried but it did not work for me.
(2) is my main problem- how to draw a custom shape or freehand line round the grouped shapes.

I try to post a screenshot to illustrate my needs - hope it works.
There are 4 shapes - 1, 2, 3, 4
I want to have a dotted line arround 1, 2 and 3. Not arround 4.
The best thing for me would be if there was just a possibility to draw a line freehand.

Edit:
Screenshot does not work.
Very easy: 4 rectangles
First line: 1, 2
second line: 3, 4
