Original Due Date as first value provided for Due Date

Question

Hi,

I would like to set an automation that will populate into custom field "Original Due Date" field value from Due Date, but only when it was first provided (initially planned).

Meaning:
Due Date field was empty and Due Date field value is updated for the very first time, the value of Due Date should be populated to "Original Due Date" field.

I have created a rule that copies Due Date to "Original Due Date" when issue is created, however Due Date field is not required, therefore this rule is not sufficient, as Due Date might be provided later.

I do not want to update Original Due Date when Due Date is updated (when value was once provided).

I am wondering if there is possibility to get to such smart value that holds information about first ever due date provided for issue?
