Is there a way to bulk-load notes to organisation records?

I've recently imported a few thousand business records. I want to include a note with each to state the data sources, so that sales reps can understand this when they go to contact the prospect.

Is there a way to do this, or does it have to be another custom field? It's preferable to be able to add this as a note against the organisation record.
