creating a hook for wrappers ?

I’m creating blocks and would like to remove the block label. Initially I just cloned a wrapper renamed it, then removed the name link. I’m realizing as I learn the API that modifying the actual files may not be the best way to do this.

Is there a way to create a hook for wrappers ? if so how ?

You should just be able to add a new file with the wrapper info you want and then just select it as the wrapper. This will NOT be in conflict with future upgrades.
