You can't do that.  Custom properties are assigned to objects, not to 
the contents of those objects.  There are a few ways to accomplish what 
you are trying to do, though:

- - You could use a custom property on the field itself to store the 
extra information for all of the lines in the field (scrolling list).  
Each line of the custom property could represent the corresponding line 
of the scrolling list, for example.

- - If each line in the scrolling list is guaranteed to be unique, you 
could use a custom property set as if it were an array, using the 
content of the scrolling list (which may be a string, it does not need 
to be a number) as an index into the "array", and storing the other 
values in the array.

- - You could use a separate, hidden (if desired)  field to store the 
extra information

etc.
