If I understand your question correctly, you wish to automatically set corresponding data based on a choice by the user? You can do this in a microflow. For example set a ‘Call a microflow’ event on the reference selector that you use for selecting your location. Then gather all your data in the microflow and change your object accordingly. Do a page refresh if you want to show the changes to your user.
If you only wish to show data to your user, perhaps a ‘Master Detail’ Layout is more suitable.
