Custom properties for Activities (Tasks, Meetings, etc.)
We currently have custom properties for contacts, deals, companies and tickets. We need custom properties for activities too, which means custom properties for task. Any serious task manager like Asana or Trello offers that.
It's going to all allow finer management of tasks, calls, meetings, basically all activity types which a pre-requisite for activity-based workflows: https://community.hubspot.com/t5/HubSpot-Ideas/Activity-based-Workflows/idi-p/204852
As different activity types (calls vs meetings vs tasks) require different information, Hubspot should allow Admins to select which customer property applies to which activity type.
