Restrict recent purchasers who's order is in transit from getting flow messages

Hi,

I want to filter out from the flow customers who have purchased in the last 30 days AND did NOT received their order yet. In other words, I want to include buyers who received the package, no matter when they placed the order.

I just can’t figure out how to write the filter. 

It could be done using conditional split, but I don’t want to use it, because I would get to active branches that need to duplicate the content.

Another workaround I came up with is create a separate flow to enrich profiles and tag buyers when they receive their order. But I am not a fan of this method, because tags not work well, at least for me. It would add a lot more clutter, in my opinion.

Maybe someone has a very simple idea to solve this?

Thank you.
