 - **Add a new property name and assign a value:** If you want to create a new property and set a static value, use [Segment's Public API](https://docs.segmentapis.com/tag/Transformations){:target="_blank"} to create `new_property: static_value`. Segment currently supports setting static values for top-level fields with `propertyValueTransformations`. However, Segment doesn't support changing fields outside the properties or traits object with `propertyRenames`.
 
-- **Change property value casing:** Transform property value casing to lowercase, uppercase, snake case, kebab case, or title case. For example, transform the property value `united states` to `USA` to remain consistent with your data tracking.
+- **Change property value casing:** Use [Segment's Public API](https://docs.segmentapis.com/tag/Transformations){:target="_blank"} to transform property value casing to lowercase, uppercase, snake case, kebab case, or title case. For example, transform the property value `united states` to `USA` to remain consistent with your data tracking. You can transform these properties using static casing functions (`"uppercase("United States")"`) or dynamic casing functions (`"lowercase(property value 1")"`).
 
+- **Create a new property**: Use [Segment's Public API](https://docs.segmentapis.com/tag/Transformations){:target="_blank"} to create a new property and set the value of the new property to the transformed value of an existing property. For example, create a new property (`prop2`) with a value of `lowercase(properties.prop1)` by including `prop2: lowercase(properties.prop1)` in your payload.
+
+- **Replace the value of a current property**: You can replace the property value of an existing property using static casing functions, for example `prop1: "titlecase(value 2)"`, or dynamic casing functions (`"prop1: kebabcase("properties.prop1")"`) with [Segment's Public API](https://docs.segmentapis.com/tag/Transformations){:target="_blank"}.
+
+- **Change the value of a property if a user triggers an event:** Use [Segment's Public API](https://docs.segmentapis.com/tag/Transformations){:target="_blank"} to dynamically assign the value of one existing property to another property, or assign the value of an property to a new property. For example, you can assign a new property, `property2`, to have the same value as `property1` if a user clicks a button.
