Placing different Images into same Image background object

[Sivakatirswami]

Grouped-background Text fields, by default have a their "sharedText" 
property off. Without knowing the insid" of it, on the surface we have 
a single object with a single ID in a stack serving as a container for 
multiple data.

Can we make an single image perform similarly? I haven't found a way,  
so I guess this is a feature request... is this on anyone else's wish 
list?

: a single image object in a background such that on new-cloned cards 
with the same placed background, that one image object could display  a 
different externally referenced image- or be a container for imported 
pixel data.

Using the field model, what is wanted is a single image object, one ID 
only in the stack, whose "sharedBinaryPixelData," when part of a 
background, is off.
