Thanks for the feedback. Having a template with all of the different block types could be a useful addition to our template library. You can vote on the idea here in our feedback area. Have you been trying to insert the same type of block into different templates, or are you looking for a specific block that is only available in some templates? Most of our Basic Pack templates have many different options available for block types.
As a workaround, if there is a block type/layout that you are looking to have in a template you can copy the HTML from the block and paste it into a block in the template that you are working in.
