event tracking groundhogg

Hi there, I send this feature request to add information to the event tracking.

I noticed that with tracking I can only add a few pieces of information, while with groundhogg I can add meta data.
It would be useful to have a single order_received custom activity with order subtotal as the value of the custom activity and meta data like:
order_id:
order_total:
data_created:
data_completed:
products: , (products in a single field; otherwise, I can’t select the meta_key as a wildcard in the contact filter)

Thank you
David
