You can duplicate a published post which saves to your drafts. This allow you to easily re-use templates instead of reformatting each post from scratch.
1. On any published post, select the three dots next to the title. From the drop-down menu select "Duplicate to drafts".
2. A copy of the post will automatically appear in your Drafts on your Posts page. The duplicate post will be labeled "Copy".
3. Click on the draft and edit as you'd like such as changing the title and content.
Note: Any paywalls in the original post will also be copied over to the duplicate draft.
