Ability to set the 'other' value for a choice field

[AHelms]

Currently, you can only set the value for a choice field as though it was within the defined pick list. This can lead to some visibility issues when viewing the data on the web app.

Additionally, there are also some use cases where a user would like to be able to set the 'other' value of a choice field through a data event. Having a SETOTHERVALUE() function would be very helpful in these situations and may be more ideal than using SETVALUE() if the value is not a defined choice option.
