Experience:
when I was adding a Frequency Module there was an option to set the default survey duration which I set to 60 minutes, then I thought about the possibility of changing the duration after discussions with the team but I couldn't find a tool to change it either in "Project Modules" menu or the "Module Settings".
Feature change:
It would be practical to have this option back as in the older RL, possibly in "Module Settings" --> "Frequency" tab --> "Frequency Sampling Targets" table --> a new field for the "Survey Duration"
