# Unsupported Features ## Totals ## Crosstabs Cross tabs must be redesigned by hand because the implementation of cross tabs in Report Builder and List & Label are too different. They are not supported by Ice Porter. ## Lines and Boxes Unfortunately we do not port lines and boxes because of a bug in Report Builder's COM interface. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
