New short codes for different date formats

It would be nice to have short codes that allow you to achieve outputs like "August 12" and "08/12/2025".

Current functionality:
%check_in% – gives "Friday, August 12"

%check_in_day_of_month% – gives “12"

Requested functionality:

• %check_in_month_date% – gives "August 12"

• %check_in_month_hyph_date% – gives "Aug 12"

• %check_in_MM_DD-YYYY% – gives "08/12/2026”

Reasoning: in my internal team and external guest communications, I’d like to simplify the messages by removing the day of the week. This is especially true for email subject lines and SMS, where brevity is appreciated (e.g. “Reservation confirmed for Aug 12 - Aug 17”)

Airbnb’s reservation confirmation email notifications function similarly — when I receive a new guest booking, I receive an email with the subject “Reservation confirmed - Jane Doe arrives Aug 12”
