Adding mfg part to Part AML via MCO

I can, and do use Simple MCO to add manufacturer parts to the AML of a particular part, let's call it Part A. However, if Part A is already on the BOM of a higher level part, after the Simple MCO is released, the higher level part then shows Part A at "Manual Change" instead of the newly released adjusted part.

Is this something that is to be expected?

How can I make it so that when a part is modified via Simple MCO, other higher level parts that may have that part on the BOM don't say "Manual Change"?

I am running Aras Innovator Version 12.0 SP9  Build: 24090 in case it matters.
