Deferred Expenses - Global Accounting Engine - 11.5.10 and 12

In 11.5.10, to use Deferred Expenses in AP, you must create a Document Category for AP invoices with such type of expenses, and link it in the setup of AP.  You are allowed to link only one Category.  Since the category must be indicated in the VAT register, this means this category can only contain invoices of one type (either those that must appear on a specific VAT register, or those that don't); therefore deferred expenses can only be managed for one type of invoice.

Is my observation correct?  Is there a way to manage deferred expenses for, let's say, domestic invoices AND foreign invoices?
