ImportType 0 - cannot insert NULL into attribute with length less than 6

We are trying to set a Text attribute of length 2 to NULL.  We cannot use Import Type 2 because we have two different sources for the entity. Each source populates different attributes.

When using ImportType 0, you need to write the string ~NULL~ to set the value to NULL.  This is not possible because the column in the staging table is nvarchar(2).

Is this going to be fixed?

Perhaps including a bit field to set values to NULL could work, as per Olof Szymczak's suggestion on the TechNet article?
