Data import set a field to blank

Hello,

Some of our users want to use Data import for updating data. While doing so, they routinely need to set values of some fields to blank. From what we know, that’s not possible as of this writing.

Is there a way/workaround to do this? Is there a reason why this cannot be provided? Or can it be provided with some known quirks?

Thanks,
Vamyip

Bump!
