resetting invoice number on new year beginning + grouping by year old invoices

Dear Zoho gurus,
is there a chance to auto reset invoice number on the new year beginning?
If yes, how that can be achieved.
What's more, how could I group my old invoices (2011) under a folder or something like that.
Now I have 2012 and 2011 invoices all together and that is a bit confusing for me.
Any hint please?
I am a paying member and I thought that Zoho Invoice could generate hitorical archives of old invoices automagically.

Thank you very much for your precious help.
Francesco
