Hey Thomas,
You have a good point. We are aware that the ability to apply load rules to Tags with OR logic would be very helpful. I would like to say that this ability is coming soon, but I don't have any solid dates to give you. Keep an eye out, though.
As a course of action, I suggest that you reach out to your account manager about adding the ability to apply OR logic. The more channels that requests for features and enhancements come in from, the more likely they are to be prioritized.
I sincerely hope we address this soon!
Thanks,
Seth
