Can I filter by last person commenting on an issue or time the comment was made?

[Laura Merino Diez]

I was looking at a filter for issues updated a month ago or longer. Then I used the bulk edit to making a comment about closing those issues. 

What I did not realize (silly me!) is that that by commenting I was losing that filter (since I updated all those issues. 

Is there a way to:

1-Undo my bulk edit?

2-filtered for issues last commented by me or commented at a specific time?

Thanks!
