How createAnObject withinAcell and keep it's size percentage wice to the cell?

Hi.

I need to be able to create an object within a cell, and the object should
adjust it's width and height in relation to the cell width and height.

I have tried this using Picture and Label but these objects to not
get any wider/higher than the initial width and height. It only shrinks with
the cell if cell get less height and/or width than the object.

So is there an object to use, I must also be able to set a color for the object.

On creation I would like to do the following:

Set top and left in relation to the cell top and left.
Set height and width in percentage. The percentage should be related to
the width / height of the cell.
Set a background color for the object.
Optionally be able to put a character or more centered within the object, similar to to the label object.

Any native Excel objects that can do this or eventually third party objects... I do not care if I have to pay a small fee in order to get the object or control....
