Simplifying blank entries
I'm wondering if there's a way to blank out the "year" or "place" on all entries without having to do it manually one at a time. I'm doing batches of 1000 entries, and it's tedious to enter a blank, thousands of times instead of just being able to have a blank automatically get entered for all entries that need a blank (ie: I don't know the date or place for the entire 1000 people). Am I missing something? Is there a way to do that or is it impossible?
