Add field event that runs when field initialised
This should be simple enough to do. Use case is a field that has a change event on it that updates another field. However the other field may start out as an empty value and so it won't be updated until the first field value actually changes. This new event would allow a script to be run when the field is initialised (ie: the startup of the form) so that a value can be populated in this field.
NOTE: This script can then choose whether or not to actually update the value based on whether it is empty or not.
