For Dropdowns on a new Form, when "Clear" is selected, reset the field such that Initial Value is active again

[WillowMobileSys]

Consider an example Form with two dropdown fields - Field A and Field B. When Field A is selected, Field B uses the Initial Value expression to automatically set its value based on that chosen in Field A.

The user has the option to manually set Field B bypassing Field A.

Now consider the case where a user chooses (or changes) a value in Field B and realizes this was a mistake. they “Clear” Field B and then choose the desired value in Field A. Field B now no longer automatically sets with a choice in Field A.

I would like the implementation of “Clear” to change such that on a NEW Form, it resets the acted column as if it has not been edited by the user at all
