Invoice Status Labels

I have customers who must receive a copy of a PAID invoice.. Am I correct that there is NO way to change the status names for invoices?

for example:

Current Zoho Invoice Invoice Status:

Draft      change to:      PENDING
Open     change to:       OPEN
Sent      change to:      EMAILED
Void       change to:       VOID
Overdue change to:     PAST DUE (dont most US Businesses Use "Past Due" when referencing invoices rather than "Overdue"?
Closed   change to:      PAID

and if this is not available I am sure your response will be that there are to many other enhancements that you are working on and this is not one of them.. THEN WHAT ARE ALL THESE ENHANCEMENTS THAT YOU ARE WORKING ON... THIS PRODUCT HAS BEEN OUT FOR 3 YEARS AND IS LACKING BASIC FUNCTIONALITY.
