Ability to add multiple contacts on the "Customer" section of KashFlow Merged

I've just finished a call to a free trialist who has a company (rather than an individual) as a customer.

However, he invoices different people within that company, but on the KashFlow customer details page, there is only the ability to add one set of contact details for that customer.

If you're invoicing people from different departments of an organisation, it would be useful to be able to direct an invoice to the relevant person, rather than the company.
