Creating an Opportunity from a Lead

Hi

Can anyone tell me if the pop-up window that is generated when I want to convert a lead to an opportunity should be populated with the address details held in the lead information fields?

At the moment, when I want to change a lead to an opportunity I have to populate all of the address fields, contact details etc. This is a real pain at the moment because we are creating a huge amount of opportunities from our groups of leads.

I just need to know if the window should auto-populate. If it should, I can get our support guys to rectify the situation. If it shouldn't, does anyone know how it can be carried out?

Thanks
