only way to do it....

is to switch to linear reading mode. Here's a repost from another thread on how to get into linear mode-

at the top of the screen above the header, click on the link named "control center"

Once in there, look for "forum settings" under the "options" menu on the left - click on it

Once there, set "Message reading display options" to "multiple messages per page sorted by time"

Click the "submit" button at the bottom.
