How to create an auto assign to previous assignee in Jira?

[alexxkey]

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.

After creating a filter , Can I choose who will get notification about it  ? By using the filter subscription Im sending the notification to my user, can I sent it to another user ?

I am not entirely sure I understand what you mean, but you may have a look at the filter subscription documentation

From the JIRA documentation 

In the Recipients box, either choose 'Personal Subscription' (if you only wish to subscribe yourself), or select a group of recipients from the dropdown list. 
Note: You cannot select a group unless your JIRA administrator has granted you the 'Manage Group Filter Subscriptions' global permission.
