Auto jump block to next page

I have a template of some text with 2 pictures in a block wich I fill in and re-use. On each page there are 2 blocks, but how can I insert a new block on a page so that the rest of the blocks jumps too the next pages?

For example, on page 6 are 2 blocks and I want to add a new one on top, so the second block jumps automatically too page 7.
