Possible to add blocks side-by-side in Captivate 12.3?

I am working on the new Adobe Captivate 12.3. Similar to the Captivate Classic, is it possible to add two or more blocks side-by-side in the new captivate? If possible can someone explain how it can be done? Dragging and trying to place to blocks side-by-side doesn’t work. Nor am I able to reduce the width of the block (though the content width can be adjusted, this doesn’t reduce the block width).
