Vendor account and check memo disassociation

in quickbooks the memo line for any check is always easily able to changed for any one check without needing to define the vendor and change its account number. having it this way makes it necessary to create a new vendor each time someone wants to change the memo. the vendor account field should not be the memo field. it should be its own individual field and the memo should be able to be edited freely with each transaction. that away a new vendor would only need to be created for a vendor if the account number changes. this is really helpful.
