Reject Entire Import

For both lists and modules, it would be nice to have an option to reject an entire import if any errors are present. A similar feature already exists for lists that allows us to reject imports on the basis of duplicate line identifiers, but expanding this to reject the import if any errors exist would be extremely helpful.

When importing data from other modules or flat files, sometimes formatting of the source data can change without or knowledge (i.e. SQL script error from an external system or a line item accidentally gets deleted/renamed in a source module). In such situations, we have know way of knowing we are importing bad data until an end user notifies us (which is NEVER a good thing). If there were instead an option to reject entire list/module imports that display errors, this would save us from importing bad data and distributing to our users.
