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

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.

Yes that is the solution. Now I remember I did that somewhere in one of my local GS websites. I just can't find it anymore have too many loose projects spreaded over my usb-sticks. I am sure this solution is somewhere in the forum where I must have found it. Thanks for posting this solution multicolor.
