"Oldest" button on discussions section

Hi! In each of our "My Discussions" sections (I mean an area like this: https://www.khanacademy.org/profile/DreamurrYayurrr/discussion/replies), we have the "Top" and "Recent" buttons, but no "Oldest" button or any way to get to your first/oldest comments/threads/questions.

It would be nice KA could add a feature like this so one doesn't have to scroll for an hour or so through 2,000+ comments/threads to look for something, or delete chats (in the case of being off-topic and asked by a Guardian to clean up your comments). 

I know it's a small feature, but it would help a lot. It gets annoying to have to scroll through months of chatting to delete whatever violates KA's guidelines or look for something you once said for whatever reason. Thank you(if you guardians see this) in advance!
