Setting up two types of column set models running at the same time

I would like to set up two types of invoices:

  1. One with the following columns : Article, Description, Type, Taxe, Unit Cost, Quantity and Total;
  2. The second one with : Article, Description, Type, Taxe and Total.

When setting this up, i could only chose one type even if i create a seperate invoice design.
Is it possible to have two types of invoices columns setting running at the same time ?



One option is create a separate sub-company under the main account.
