Option to "Hide Overriden" when customizing text overrides

My thought is to just not show those settings I’ve edited.

Issue is I’m having difficulty finding settings I haven’t yet changed since only first 50 items are returned. There is no option to continue browsing through items beyond the 50 results shown. Instead, I’m asked to “refine my search.” Unsure of best way to make it easier to filter through when changing a complex name structure in Discourse such as the word membership and member as it pertains to our forum.
