At the moment for commercial properties we have to enter a number for car parking spaces in key deatails box

Most of our listings have public car parks and not designated car parking so we say in the text of the listing - Ample parking available or on site parking - however when listings go up to commercialrealestate.com.au we cannot type text in Rex - key details car spaces it has to be a number. We then have to leave as zero as we have no idea the number of car parks available - this then means our online listings have no parking available shown on the online ad - other agencies that use other CRM have text in this box so was wondering why we cannot do this in REX
