Changing object size based on field value

I wish to have a way to dynamically resize object on the layout base on field value (similar to charting) but for different purposes.

Exp.1 two fields, one has value 5, other 9. I need third object to start at 5" from the edge, and ends up 9" from the edge of the active window. By changing the values in those two fields, I need the third to change dynamically.

Exp.2 one field, value inside 4. I need the object to be 4" long. You change the value to 2, than the object should resize to 2".

Than I would like to see in FM10.
