Schedule A Job For Certain Day of Certain Month in Specific Timezone

Hi.

I've been trying to find out how do this, but all evidence seems to indicate support does not exist. I'm trying to do something like this:

schedule.every().day.at("09:00", "June, 1", "US/Eastern").do()

or

schedule.every().year.at("09:00", "US/Eastern").on("June 1").do()

or

schedule.every().june(1).at("09:00", "US/Eastern").do()

is this currently possible, and if not can this suggestion be considered to be implemented? Also any reasonable workaround for it until it is implemented?

Thanks
