Custom "Change Price Button" with reasons of the change

Hi Everyone,

Following threads on Gift and Void reasons, I am looking for a custom button for changing prices also recording reasons for the change for future reference.
Could someone give me hints.



Click on search and enter void reasons press search then click on tutorial and read/follow it. Then use that logic for a change price button. Your action will be update order action.

Ive implemented this already, tutorial on its way
