How to flag multiple orders from the same customer for packaging in WooCommerce?

Sometimes Customers orders (as guest, not as logged-in users-accounts) and then shorty orders again other products in our woo commerce store.
Especially on weekends.
So we got multiple orders status processing from the same person and we would like to send it together in one package.
But with a lot orders processing (30-50) it is hard to identify orders from the same customers.

so it would be nice, if a order is processing and has the same name or email-address as another order in processing, that it is flagged with an icon or something like that.

is this possible?

we already altered the function php with some code to highlight if an order is international shipping.
