Hello

Recently I finished to customize my invoice report with jasper-report, it works fine for Sales Orders but I don't know how to set that report as the default for each generated invoice from the POS. 

If I try to sell somethig from the POS and invoice it, the default invoice report appears, I want to replace it with my customized one.
Do you know how to set a jasper-report as the default report for invoices?

Thank you in advance. 

Regards
Alejandro
