[support] Prefill body textarea at node creation

Hi,

Is there a module that has functionality similar to contemplate, but instead of modifying the teaser/body after the node creation and during the node's display, the body textarea is prefilled with the text of my choice? What I need to have is when a user visits the node/add page, the body textarea must be prefilled with text that has been set somewhere in the administration area. For this particular application, this text will be a pair of signatures and since there will be a number of nodes using these signatures, I figured out that a good solution was to have the body textarea prefilled with the appropriate html snippet. It will be the user's preference to keep it or delete it.

I hope that makes sense.
