Hi @NMackay,
No, this is currently not possible but has been requested by many users before: https://community.hubspot.com/t5/HubSpot-Ideas/How-do-you-duplicate-a-Deal/idi-p/15263
The product team reviews these requests based on their popularity, I’d recommend upvoting and commenting. You can also help others find the request more easily (and drive traction) by accepting my reply as a solution. I’d appreciate it, too.
As far as workarounds go, you could continue manually, use workflows or leverage third-party integrations: HubSpot Marketplace
A note from the moderator: There are a handful of third party apps suggested by Community members in the thread below! While this feature is not yet native in HubSpot, the apps below could be a great alternative.
Best regards!
