Note this is a complex question, with a complex answer I don't quite understand, but it seemed important enough to put here until someone rewrites it!

Hi John,
I think the easiest solution to this problem is to modify
/admin/se_mapping.php and /include/feeding.php3 scripts in order you can map the
id.............. and short_id........ fields too. From my first look I think, it
is not so big problem to show Id and Short Id in "From" column of
se_mapping.php3. Then you just create any "Child id" field in PARENT slice and
there you will map the short_id (or id) of item in CHILD slice.
