Hi there,
we’ll be introducing a template feature in GenerateBlocks Pro which will make this super easy.
In the meantime you have some choices.
Simplest is to select the Block and CTRL-C Copy and then CTRL-V Paste in to your new page.
Other option is to duplicate the container block, then convert your duplicate into a Re-usable block ( from the 3 dot menu on toolbar ). Now you can add the re-usable blocks to your other page and then convert them to a Regular block for local editing.
