You can modify your evaluation anytime you want... You can add the date you make your evaluation and next time you visit the place you can modify your evaluation starting with the new date. I prefer having the last evaluation on top of the previous one separated by a line. You can add several evaluations for the same place 🙂
Hi @daleonm, thank you for sharing this idea. It is not something the team is able to implement at this time; therefore, I will change the status to "Closed".
