Is it possible to have the dialog to schedule an appointment within the lead conversion page?

We are a contracting company and we do a free estimate for each deal/potential.
Every single time a lead is converted to a deal we need to schedule the first appointment with them.

Having to convert the lead first then go in after and schedule the appointment takes a while and is accident prone. 
Is it possible to add this option onto the lead conversion page? Or to have the lead conversion page redirect to an scheduling page with fields prefilled?

I am new to Zoho and am still learning some of the more advanced features.
