Project Invoicing problems

We are trying to set up a global invoice template for multiple companies set up in Axapta. This is proving difficult since what is required in one company does not satisfy the others. Is there any way that more than one template can be set up. With different defaults for each company. Specifically this relates to Project invoicing for which we are using on-account invoices, however this may also apply to invoices generated from sales orders in the future

Are you talking about a report template, or different report designs ???
