Assign a child product to two parent products

[heypachuco]

Hello,
I'm trying to assign one child item to several parent items.
I have a power supply that is a child item of an item we sell, and it can be used with two new item we will start selling. I was trying to figure out how to assign this power supply as a child of both items.
Aside from creating multiple copies of this item (with unique SKU's), is there a better way to accomplish this?

Thank you.
