How to default Location field even after the submission of transaction?

Summary:

Hi experts,

we are trying to implement an autocomplete rule that defaults the Location field to the previous location value.

For example:

If Location was set to "A" (which happens to be the previous location inserted) , is it possible to restrict/default to this value even after a Change Position action where the location is synchronized automatically with the Department?

I've tried using Object Defaulting Rule type but failed to default Location field to "A" as the pop-up overrides the values. Is there a way to default back the previous value in spite of the pop-up and even after submission of transaction?
