Targeted Cross Sell

Hi,

I would like to set up a flow that allows for a specifically targeted cross-sell. We have lots of sets of clothing in our store eg - hoodies & track pants, tops & skirts.

I have all of this information set up in Shopify under the 'complementary products' meta field. Thus, all of the products already have this information so how I would like the flow to work is that:

1. Somebody buys the top
2. An email is sent X days later cross-promoting the matching skirt and offering a discount

I began setting up a flow for every single product however this is a tedious task and I expect that because Klayvio has all of the Shopify data, I should be able to set up a flow with specific cross-selling.

Please advise on how to set this up.
