Remove the event price

Hello again
Is there a simple way to disable the pricing section, so that it doesn’t default to ‘free’ when people click through. Most of the events I’m adding have several price points, including concessions for juniors, and the pricing section is not able to cope. I’ve been putting the prices in the main event panel, but as you know if you untick ‘free’ it wants a single price?
All help appreciated …
Andrew
