Hi BetsyP1!
Thanks for reaching out to the Community with this question! I am excited to tell you we are currently tracking a request to have vertical dividers as an independent block element. I have tracked this on your behalf and we will send you an email once this feature has been updated.
In the meantime there is a workaround you can use with 3 columns. Use the layout containing the vertical divider. Other elements (text boxes, images, buttons, etc) can be added or removed to customize the layout as needed. You can also add a 3rd column to the layout, which will be separated by another vertical divider! Just drag over a text box, image, or button and drop it where you want that 3rd column. I noticed when I tried it in my account that I needed to add a spacer above the 3rd column image to make it match.
