Shopify does not understand inventory variable and over add to cart. ETSY RELATED

I am syncing etsy store to my shopify.
My variation

Variable 1
white pendant quantity 2

yellow pendant quantity 2

Variable 2

necklace 14 quantity 10

necklace 16 quantity 10

I want to be able to set 4 pendants and 20 necklaces as variables together. Once my 4 quantity of pendant is sold out , the post will just say sold out even though there will be chains remaining. Shopify doesn’t understand and would allow customer to add 2 white pendant with size 14 inch and 2 white pendant with 16 inch necklaces into their cart. This results total 4 white pendant when I only have 2 available .Iv tried bundling with apps like Trunk inventory without success, Trunk tech said there app only understands once the item is checked out. Etsy is very limited on inventory options so I would have to start with etsy and make shopify work with it. I have included photo of how my etsy inventory is set up so customer can purchase pendant with necklaces or without. Is there a code I can plug-in? I have tried apps such as order limits minmaxify, they require manually input but I cannot input all because I have a lot of products / variants
