In Q you can customise Column Comparisons to compare specific columns ([https://wiki.q-researchsoftware.com/wiki/How_to_Specify_Columns_to_be_Compared|https://wiki.q-researchsoftware.com/wiki/How_to_Specify_Columns_to_be_Compared]). However, this functionality has yet to be added to Displayr which only allows default Column Comparisons with no means to customise.
