Expenses & Non Expenses Accounts

Dear All,
If we buy Fixed Assets for company in expenses section for example there is no Assets Accounts only expenses in the accounting module ,in this case we can not buying assets from journal section because we must make payment voucher for vendors, we can not give vendors journal entry and send to them because it is unlegal document
i hope to put all charts of accounts in expenses section not only expenses.
Sincerely
Webbo
