We have multiple contact people for each company we do business for. They look after separate activities and we would like to keep invoices separate for each contact but still under the same company umbrella. There is currently no option to select from a set list of contacts for the same company. You can add contact persons to each customer/company but when making an invoice it's impossible to select just one person to send a specific invoice to. It's a bit ridiculous really because Zoho gives us the option to select our own salespeople from a dropdown list but not for customers!
