Tick a “Pass Through” check box on the “Available Inputs Column” on a Fuzzy Lookup Transformation using BIML - sql

Question

I am using SQL Server 2008 BIDs / BIML, how do I tick the check box on the “Available Inputs Column” on the Columns tab of the Fuzzy Lookup Transformation Editor, column name is inputFile_id?
I do not won’t to match on this column just pass it through the FLT; simply tick the inputFile_id “Pass Through” checkbox on the columns tab of the Fuzzy Lookup Transformation Editor. Hopefully below a screenshot of the checkbox.
