Possible to change default potential name when converting?

Possible to change default potential name when converting?

Hello,

I'm wondering if it's possible to change the name of the potential that is inserted when converting a lead.  Right now, the potential name defaults to the name of the account.  I'm wondering if I couldn't change it to something like...

${Leads.Event Date}-${Leads.City}, ${Leads.State}

Not sure if there a place to change it.

Thanks in advance for your help.
