Hello. I am trying to figure out this SBA addon. My question is, say I have 3 pink shirts (S,M,L) and I have 1 of each size. These shirts have a monogram on them. Say I also am using these same 3 shirt for a different product that has a different monogram. Since these will be personalized I don't make them upfront.

HOW do I put the stock of these attributes when they are used on different products using the color attribute to define what is in stock.
