Hi there Michael!
Don here from Shopify. :)
Apologies for the slight delay in getting to you here.
As we're only able to support the use of a Facebook pixel in your store you would need to look at getting some outside help to put this in place for your store.
What you can do in this situation is to consider hiring an Expert Designer who would be able to help you to put a custom solution in place.
You can either browse for Expert there yourself or post a job and see who approaches you for that task. :)
We're also available via our support site if you have any other questions about using Shopify at any point.
All the best!
