XF 1.5 When Reading Already-Read Thread, How To Be Positioned at Bottom

1. Click on a thread or conversation that contains messages you haven't read - XF takes you to the first unread message.

2. Click away to something else.

3. Come back to the thread or conversation you started with, and when you open it, you are at the beginning but would rather be at the end since you need to reread the most recent message.

Is there a way to make this a default behavior, a check-box in the ACP that says, "Take user to last read message in an already-read thread." This would save me clicking on the last page number in the thread and then scrolling down.

Thanks in advance for your advice.
