Ability to use custom content group types (as part of Tracking Code installation)
There are currently only a handful of very basic valid value options for content groups / content types, as part of HubSpot Analytics. The currently available options are listed below, as per this HubSpot article:
standard-page OR site-page
landing-page
listing-page
blog-post
knowledge-article
It'd be great if these groups could be expanded to account for common e-commerce use cases (e.g. "product", "product-category", "checkout" etc.). Ideally, however, I think a more robust solution would be to offer the ability to define and report on custom content group types. This would leave it wide open to all website types / use cases.
