Combine multiply orders into one with Flow

[Davis_XI]

We are currently getting a lot of orders through from TikTok for free samples but each request is hitting Shopify as a separate order. Is it possible to create a Flow which detects if there has been an order form the same person in a certain time frame and then groups them to the same address?

I have the below template which I think could work but I don't know how to get the last action to combine orders and send to the same address.
