I don't know how create auto assignment to previous assignee using custom field and post function when I change issue status (or dragging it to other status column on the board). Here, at this community a read other comments, but there is still no clear understanding except "create custom field" and use post function.
Can somebody explain me how to do that in detail? Like "chose that menu, click certain button, then go to some settings etc"? I can use post function to assign next assignee, but don't know how to assign previous.
Here I illustrate what I mean.
Thanks in advance for help.
