BCD436HP Am I using Sentinel correctly?

I have a feeling I'm overlooking something. Long ago I created all my favorite lists and they work fine. But when I download the weekly master DB update, how can I know which (if any) of the systems, TGID's, control frequencies that are in my FL's, need to be updated? Is the only safe method of updating my FL's to delete and re-create them (along with all the customizations I may have done to them)??



Surely the software includes a better way to either update FL's automatically, or at least make it possible to compare/identify the changes so that they can be applied manually. Any help will be appreciated!
