HubSpot Active List + Engagement Tracking Setup

Project Overview I am looking for a HubSpot expert to help build a scalable engagement tracking system within HubSpot for a specific content topic area: Mating Disruption / Moth Block. Immediate Goal I have two marketing emails that were sent from HubSpot. Both contain a link to the same PDF article related to stored product moth management and mating disruption. I need an Active List created that automatically includes contacts who clicked that specific article link from either email. List Name: Mating Disruption Interest Requirements Phase 1: Initial Active List Create an Active List that includes: Contacts who clicked a specific URL within Email #1 Contacts who clicked the same URL within Email #2 The list should automatically update if additional qualifying criteria are added in the future. Phase 2: Scalable Structure I would like recommendations and implementation for a scalable approach so future Mating Disruption / Moth Block engagement can be added over time, including: Email clicks Landing page visits Form submissions Resource downloads Webinar registrations Other related engagement signals The goal is to maintain one master audience of contacts interested in Mating Disruption topics. Phase 3: Reporting & Visibility I would like either: Option A A custom HubSpot report/dashboard showing: Contact Name Company Email Date of engagement Content engaged with Engagement type (email click, form submission, page visit, etc.) OR Option B A recommended HubSpot property structure that captures: Date of first Mating Disruption engagement Most recent Mating Disruption engagement Content source or content title Please recommend the best approach. Deliverables Active List: Mating Disruption Interest Recommended long-term architecture for tracking topic-based interest in HubSpot Dashboard and/or reporting setup Documentation or short Loom video explaining: How the system works How to add future Mating Disruption content to the audience How Sales can use the audience as a call list Environment HubSpot Marketing Hub Professional Existing marketing emails already sent Existing PDF article link already available Looking for a solution that is simple to maintain by a marketing team Please include your HubSpot experience and estimated time to complete.
