Loop thru metadata?

[osseonews]

Is there a way to loop thru metadata as a variable in a template? For example, we were thinking of storing a list of products in metadata for an ecommerce lead (abandoned cart), then in the template we want to loop thru those products and have it show in the template, like: you forgot the following items in your cart...I know we can just do this on the backend and create HTML and send it via a transactional email, but it would be easier to create template that we can reuse and just send the email via an event and action. But, couldn't figure out how we could actually create a template that would loop thru a metadata object. Thanks.

There is no syntax to do this inside of Plunk directly
