Can I run though all products based on date in a metafield?

[mns-burg]

Is it possible to make a Workflow that runs through all products based on a metafield?

Our products are maintained form an external database that synchs its data with Shopify.
We have a metafield that holds the date for the last synchronisation.

Our problem is that our database sometimes have a problem with synching up. I therefore want to create a flow that informs if the the last synchronisation date is over three months old.
Anybody have an idea of how to do that purely in Shopify Flow?

I believe it is possible but I am not too sure on how. Maybe some experts can help you with the detailed information on this case
