How to batch layer updating?

[Davec43]

Currently I have over 100 feature layers that need to be updated that all have different names. Annually I take a layer that covers a large geographic area and trim it and separate it into smaller layer files with using a select by location.

Is there a way to automate this?

If the geographic bounds have a named attribute then you may be able to split it into its constituent parts using

Thanks, that seems to be the path. Only issue is there's multiple overlapping with different names.
