Select either "Event Property" or "User Property" to open the property builder. 3. Optionally, give your property a name. 4. Click into the formula bar to start defining your custom property. 5. If you're new to this feature, you can click the "Insert Example" dropdown to populate the box with a use-case specific custom property. 6. When writing your formula, use Ctrl + Space to see a list of available functions and their descriptions. 7. Use the period (.) key to search for event or user profile properties to add to your formula. 8. Click "Apply" to use the custom property locally in your current report. 9. If you want to save the custom property permanently for use in other reports and make it available to other project members, click "Save".Note that custom properties are local to the report by default when you select "Apply". It's recommended to test the custom property in your local analysis before saving and sharing it to reduce clutter in the project.When saving, you can add a description and choose to share the custom property with specific colleagues, teams, or the entire organization by clicking "Save and Share".Remember that the formula used to create your custom property can't exceed 20,000 characters.Creating a Custom Property
