Edit DNS Zone Error Loses Data

When editing a zone, I frequently add 10 records at a time. I'm glad we have multiple input boxes for that. Wouldn't it be helpful, though, that if there's an error when saving the zone, like a malformed record, that the system repopulates those textboxes instead of forcing you to re-enter every bit of data you previously did? It seems like an obvious reaction to bad input. I don't mind the unhelpful parsing error message, but this annoyance goes a bit too far, in my opinion.
