Using Secure Box and scrolling to end of page

[CyberSurfer409]

Hi,
I am trying to move certain text messages from my general SMS folder to the Secure Box. I know I can select 'Move to Secure Box' and then scroll through all the messages (starting with the oldest) and select them. But is there anyway to do this as messages come in. I have one message thread in particular with over 8000 messages and scrolling through all them is a pain.
With that said, is there a way from the 'select message' screen to automatically scroll to the bottom. Doing this manually takes minutes.

Thanks
