Containing one coral with another coral?

[BlazinNano]

I know it happens by accident, corals just grow together. But has anyone purposely placed a coral to grow to keep a different coral from spreading to far? Basically I have pandora zoas growing on a branch off of the main rock structure, I like them but we all know they can take over. There is only 1 way to get to the main rock structure, what able putting a different coral there to grow to keep the pandoras contained?
