I want to be able to set an activity for a meeting and have pipedrive automatically create a second activity following the first one for admin time.
Automations currently don't allow this to work.
Pipedrive does not currently allows you to reference another activity time to create a activity 2 hours after that activity.
You can use make or zapier to achieve that, if you use a specific activity type for this first event that generates another event.
Hope this helps
