If you are managing multiple "profiles" in your Travefy account, you will have the option to pick a "profile" to represent each itinerary you build.
You can find Your Profile under your Name at the top of your Travefy dashboard:
When you start building a new itinerary, the profile you have set as your default will automatically be set as that itinerary's profile. If you would like to change it to another profile, you can do this by clicking on the itinerary in your active trip's list. One the right-hand side you will then see the option to change the Presenter, press the drop-down menu next to it to choose the profile you wish to display on that itinerary.
