Is there a way to copy/paste content blocks on a page?

Site URL: http://almostallison.com

I'm working on a portfolio page to showcase writing samples. I've used one of the page layouts provided by Squarespace, but I need to add more content then the page provided blocks for. 

I was wondering if there is any way to copy and paste a set of blocks? I know I can just add the blocks in myself, but I want the images and text boxes to all be uniform in size. 

Basically, I want another row of three separate samples of writing, like the attached photo. I was hoping I could just copy/paste the top row for sizing/style, then replace with appropriate text/images. 

TIA!

Looks like a blog summary block layout. You can put a summary block, each block displays up to 30 items,  on a page and it will create the blocks by pulling content from a blog. The blog can be in the unlinked section of your site, since it doesn't need to be viewed and the text and images of each block are seperate posts in the blog. You can do this with a second blog page by the way. That is how I do it on my site. my random views

Thank you! I just selected one of the layout options when I went to create a new page, but wasn't sure what exactly it was called! Now I know! 

I don't want to pull from one place, but rather just input my own snippets from various websites. But I assume I can just add my own stuff in. Thanks so much for the help!
