Hi Sarah!
I agree that this feature would be quite handy, and am sorry to report that it isn’t something already included in our plugin(s). You have a few options to work around this at present, like manually entering the other time zone-converted times into meta field, or using the “Additional Fields” feature of Events Calendar PRO if you have it to do the same thing.
I’m sorry to disappoint on this front Sarah, let us know what you think about these two solutions mentioned above and if you have any other questions, comments or concerns.
George
