Create a 2-dimentional array choice control

Create a 2-dimentional array choice control that captures selections by coordinates (A1, A2, B2, etc. according to the box/button clicked) in order to provide drill-down granularity to large, overarching categories. Form builders would assign a category to the control, item values (questions) to rows and available choices (answers) to columns. Example application: medical provider privilege request forms include many individual privileges in large procedural bundles, each one requiring one of three possible responses.
