Are they existing hacks that would allow me to add the following two features:
- Display the custom invoice field in the invoice list as a column? I like to name my invoices based on the job description and would be helpful to have the names in the table
- I like to run a monthly report to see which categories have more sales so I have inserted a “category” custom field for each product line. Would it be possible to run a monthly report displaying totals per category? (e.g. category = sweets, chocolates, biscuits etc)
