Create Content Blocks for Beaver Builder

How could I create custom content blocks for beaver buidler similar to the set up Tyler.com has for it’s Tessaract theme where it comes with content blocks. Or even just content blocks in general that are re-usable code. If they can be implemented into beaver builder that would be fantastic. If this is not possible, how can I make something in beaver builder where there is a square photo with text to the right of it then underneath the text is another square photo lined up to the bottom left corner of the first photo and text next to that. Basically it would be sort of like this:

…………………… ————-
………………….. l………………..l
……..Text………l…….Photo….l
…. ……………….l………………..l
……………………l………………..l
…………………..————–
————-…………………….
l………………..l…………………….
l……Photo…..l……..Text……….
l………………..l……………………
l………………..l……………………
————–……………………

Except the corners touch on the photos ^^^^^ (The dots are empty space, ignore them.)
