Is there a 3.5 multi-quote plugin?

[kau]

I really like the multi quote ability in 3.6 but don't want to upgrade one of my forums because of other software & custom hacks.

Is there a plugin that allows multi-quoting for 3.5?

What hack is preventing you from upgrading? We have quite a few hacks installed and we were able to upgrade our board without much trouble.
