Yes! Duplicating a poll is a Premium feature.
- Click on the three vertical dots next to the group poll you want to duplicate.
- Click "Duplicate"
The duplicate will take over the title, the description, the location, and the proposed time slots.
However, you may need to add/remove a time slot in order for the poll to register the times (you can delete the time slot and simply add it again).
Special settings (deadlines, limited participants, hidden poll, and automatic reminders) are NOT carried over to the duplicate poll. Make sure to reactive any of these settings in the new poll.
