How to get to the top of a text conversation quickly on an iPhone?

Me and my fiancé wanted to look at some of our text messages from a year ago but hitting the 'load earlier messages' button method is taking too long. Is there any other way to do it. Faster.

You'll either has to search by key word…
or if not what you're looking for, you'll have to offload them…

You've found the best (too long) way there's.
Best luck.
