We are a consortium of 138 libraries with nearly 800 loan rules. If, for example, we decide to update the grace period for fines (something we've limited to a consortium-wide decision), we would have to update each rule individually.

I just went through our many many loan rules to set up the additional courtesy notice and was wishing the same thing. But I would, at the same time, be extremely nervous about doing this globally. I kind of wanted to see each one as I was doing this. I wonder if this would really be worth it, for the frequency it might be used weighed against the potential "damage" that can be done.

It would be helpful to be able to select a number of loan rules and make a single change to all of them. This would make it easier, and would ensure consistency.

Ideally some sort of checkbox situation, like you see when you view your email and want to delete, etc. You could check all or select specific loan rules and then update a specific field/setting all at once.

I agree with Jeremy Goldstein that this would need to be very carefully implemented. Perhaps a way to select the loan rules to be updated would help? That way, you could limit the changes to only active rules, or change rules for different types of materials in different ways.

The use case for this idea makes a ton of sense though such a feature would have to be VERY carefully implemented for sites like ours with 100's of loan rules. There would have to be at a minimum some way to limit the loan rules the global change is being applied to.
