Is there a good / preferred way to update the CustomData for multiple Inventory Item Instances at the same time? Generally, I use this to give the same information to a bunch of different items in different situations. For example, updating the last time that item was used, or giving that item a parent it would be attached to and/or removing the parent from all of the items at the same.
I don't want to have to do a call for every single item, when they are all receiving the same information. And that could add up to hundreds of calls all at once, instead of a single call. I'd rather just store an array of the InstanceIds and give them all the same updated CustomData in a single call.
I thought I had seen this somewhere once, but I can't seem to locate a way to do that at the moment. Maybe I'm searching with the wrong keywords or something.
