You will want to use the Post Library feature, and can watch our video tutorial to learn how or read this article:
Here’s how to combine more than 1 template:
First create a library for one of the template posts: In your menu, click Post Library, Manage Libraries. Then click the green Create New button. Name it the same as one of the templates and save.
Then, go to your Templates List, and open the template you just named.
Scroll to the bottom and click Copy to Post Library and select the new library you just created.
Next, go to your Post Library into that new library, and select the posts using the check boxes. Choose the OTHER template you’re adding these posts into, to combine them.
Choose your post details. To save time, just select day 1, 12:00am, then the next posts in increments of 5 minutes. You can edit this later.
TIP: If you have lots of posts on several pages, do a whole page at once before moving onto the next page.
Scroll to the top, and click “Add to Template”.
Last, go back to the template you added those posts into, and edit the added posts.
(You can also create a copy of any template, if you want to keep an original.)
