Journal Voucher Number creation

Can we create a field like JV Number(Journal Voucher Number ) for Each and every transaction(like cash,bank,Spend,Receive,Transfer,purchase,Sales,Expenses)

JV Number: Here i mean we had separate Voucher Numbers Manually created for Each transactions. I want to update the same numbers to the transactions accounted in the MANAGAR.

There is Reference field in top-right corner when creating new journal entry. Is that what you are after?
