Dallas here from the Shopify Social Care team.
Unfortunately, I'm coming in here with a short answer that isn't necessarily what you want to hear. At the moment we don't have any integrations currently or in the works with UberEats. I completely understand how frustrating that is for you! At Shopify, we're constantly working to make eCommerce better for everyone, so it's possible that something may happen in the future, but we don't have anything in the works right now.
Since UberEats is so specific in their own way I can't say that I would have a tool that might help with what you're wanting that isn't an integration with UberEats. However, if you give me a bit more information about what you're trying to achieve then I'd be happy to see if there is anything that I can find for you.
Let me know,
