plz track custom fields

In fluent crm and fluent forms, we have a lot of data but we have no chance to see the numbers of leads in fluent forms custom field based.

I use fluent forms for lead generation, and I use hidden fields to track the data source (Facebook ads, google ads, organic etc). Is there any way to see the numbers of entries for every data source in a certain amount of time?

If not it would be great to implement a such solutions in order to scale the most relevant data traffic source
