Select Timezone to display based on user vs reciever

Timezone issues & request: The timezones in Front display dates and times of custom date/time field in the Front User (ie, Employee) timezone. However, when we are communicating with our clients we communicate the time of their appointments in the clients timezone. Thus, when creating date / time fields it would be helpful to be able to decide whether we want the field to display in the user (employee) timezone or the timezone of the contact for which the custom field is associated. This impacts the employee experience as well as our ability to create dynamic text fields in message templates as we cannot guarantee that they will fill with the appointment in the correct timezone as the person receiving it.
