What would be the best way to keep an individual extent updated?

Fetching the planet, extracting the extent of the area of interest and
create my own diffs?

I could also apply the planet wide diffs and remove everything outside
of the extent afterwards. But I don't like this idea.

Is there a way to process the diff files in a way that the diff only
contains changes in my area of interest?

Thanks for any hints.
