Is there a plugin similar to multiblock to insert blocks into the content?

[multicolor]

I need to give the site editor the ability to use code blocks in page texts, like in cms typesetter. Inserting blocks into a template common to all pages is useless for me

Why you don't create seperate template file only for page where you can use multiblock? index.php - put multiblock option,  and rest subpage template.php without multiblock function.
