Showing member signature only once per topic

[Sunlite]

Currently on IPS 4, I used to have a hack that allowed a members signature to show only once per topic. Is there anything out there to make this happen?

I've tried searching and couldn't find anything.

I am in real need of this, thanking in advance.

This is abit odd. I've enabled signatures on my forums and the signatures show under that user for every response within the topic. Hmm. Hopefully someone can assist shortly, otherwise i'm sure IPS will be able too!
