Hello Franek, As Jacek mentioned, you can use a "Multiple line of text" field, then create a cycle with the "Change value of single field" to copy all comments, and finally hide the standard comments field.

Hi Damian, Where are you using this rule? You should use it in the 'Behavior' tab in the workflow and in the 'Style and Behavior' tab in the 'Registrant' attribute. Then it should work correctly.
