Register Feature from SQL Server table with bit datatype column

I'm in the process of designing a SQL Server database where one of the tables contain a column with the datatype bit. When I try to register the features in the table, Geospatial Administrator doesn't seem to recognize this column.

In the end, I want the corresponding feature's property for this column to be a Checkbox property so the end user can only select two possible values. How should I design the database table so the Register Feature will model the column as a Checkbox property?
