Invoice number change

Hello,

How can I change the invoice number and/or prefix on the new version 4.74 of Express Accounts?

I can't find it in the Setup / Invoice...

It was there in the older versions.

Thanks for any help.

It's on 'create New Invoice' window in version 4.74, in upper right 'Invoice' panel.

Can I customize Invoice number is Express 3.90 (free basic version)?
