ChemDraw: How do I "stretch" the TLC dots to make them oval-shaped instead of circular

It would be nice to be able to "stretch" the TLC dots to make them oval-shaped instead of circular, and grey instead of black. These features would enable the user to create something closer to reality.

See "The TLC Tool" in the ChemDraw manual. To change the style or color of a spot:

1. Right-click or Control click on a spot.

2. Choose the style or color. 
   NOTE: To change the style for all spots, Right-click or Control-click in the plate and choose the style from the TLC Spots submenu. To enlarge or “smear” a spot: 
   Shift+drag the spot. 

3. When you position the cursor on a spot and press “Shift”, the cursor assumes one of three shapes, depending on how it is positioned:
   
   Cross arrows –used to enlarge a spot. 
   Horizontal arrow – used to widen a spot. 
   Vertical arrow – used to elongate a spot. 
   
   NOTE: You may want to zoom in to make positioning easier.
