Notes on TfL transactions overwritten

I understand that the way TFL provides data is inconsistent and this seems to result in some notes made against pending transactions to be overwritten.

Sometimes when the transaction first appears it is still pending and has a note without the transaction date. If you enter a note at this point the note may later be overwritten when the transaction ceases to be pending and when the note now shows the transaction date.

Could notes written by users take priority over those that come with the transaction please? If I have entered a note anything added from what TFL send should be appended to the user note not overwrite it please.
