How can I have a matrix table question display additional rows based on user interaction?

Hi all! I have a matrix table question for which I would like the user to be able to specify and respond to additional "Other" choices. I'd prefer to only have one row with a blank "Other" text box statement visible at a time. For (a silly) example: Mark how many hours you spend in each room in your house: * Kitchen * Living room * Bathroom * Other (please explain) ________ * Other (please explain) ________ * Other (please explain) ________ etc., where each "Other" option would only appear once the previous "Other" option has been filled in. I tried adding display logic to the additional "Other" statements (to be displayed if the previous "Other" text entry "is not empty"), but the statements don't show up. Is there a way to do this built into Qualtrics (or any other way to achieve this)? Thanks in advance!
