I apologise if this is a known feature or problem but I am stuck:
I wish to create a block of text in the shape of a trapezium.  When I use the default shape tool all works as expected with the margins of the text following the trapezium shape.  However, I wish my shape to resemble a plastic coffee cup, wider at the top than the bottom.  When I add frame text to the inverted trapezium it is displayed upside down and back to front. Is there a way of resetting the text entry to the top left and having it flow normally?  I have tried to attach a screen shot of the problem.

best wishes Simon
