So there's the default import, by file timestamp, rather than just piling them on top of one another.... move to the feature request forum?

That already IS the default import option in SONAR - import at BWF time stamp - which is why we get a "why do my loops end up at 1 hour when I import them into SONAR?" thread every week or two. So no need for a feature request. I checked the H4n specs, it supports BWF time stamping although maybe this needs to be enabled, or the OP needs to enable "import at time stamp" in Sonar's preferences if it became unchecked.
 
These threads from other H4n owners having problems might be helpful, even though they're not about Sonar.

Do you have the latest firmware, which appears to fix an H4n BWF issue?
