How to combine several validation messages from a microflow into one message, that is shown to the user

Hi colleagues,  I built a microflow that can show several validation messages to the user in case of missing input data.  Currently these messages are shown subsequently when the user tries to go the next page but I was wondering if there is a way to show only one message window to the user that contains all errors/missing information messages? Thanks a lot in advance for your help! :)

Create one microflow where you check all your validations and create and append to one return string with all the validation errors. You can call this microflow when closing the page and if the string is empty go ahead and do whatever you want to do next or break and show the message is the string is filled.
