MDS: How to set String Value to NULL through stg tables?

I'm trying to set a string field in MDS to NULL using the staging tables. Per this documentation,, setting it to NULL will just have the field ignored when the ImportType is 0. So if you want to overwrite an existing value with NULL, you need to import the string as ~NULL~. But the field I'm working with is only NVARCHAR(3), which causes the stage table to truncate to ~NU. Is there any other way to do this?
