Easy-to-use preset blocks for non-techy clients with "add one more"

Other block builders are a lot easier to use than webwave, although they don´t allow the same control. I think for website creation, I can use webwave without problems. But now, I give access to a client who can not do much more than press a button to add a block. As you know, moving new elements into the editor can quickly crash the design, because the distances are not right, etc.

So it would be great to have a couple of elements, like features, timeline, and any type of repetetive blocks, that allow the user to simply “add one more”. I picture this to be a simple button with a plus icon. If pressed, it creates the same block as the others of this section and can be filled. These preset sections could facilitate website creation a lot. In the edit bar, you could allow to choose width, number of columns/elements, etc.

Example:

Currently, I´ve done this by getting a features block, duplicate the group twice. But each element is being rendered differently, so I need to adjust every block by itself. Imagine not to work in each element but rather in the mother element. Here, you set styles, columns, etc. to add one block, simply click a plus button.

I hope you understood what I imagine.
