This absolutley needs an overhaul. We’re also facing the related issue of merging multiple options into one. Being able to update activities as objects in a workflow would address both of these issues. (For example, meeting type C and D are the same and we want to now call them X). Merging options is also already an option for regular properties in the property settings.
Hubspot’s whole thing is “scaling your business” - having to manually update thousands of activities across different records is not feasible in a scaled business. As a result of our business having scaled, our needs have changed, meaning logged activities are exactly the kind of thing we need to adjust in response.
