I have a requirement to take a date field entered by a requester ("UDF_DATE6") and then basically copy that date information to the built in "DuebyTime"

While this can sort of be done with field / form rules scripting it requires editing the ticket again since "DueBy Date" does not exist until the submission of the ticket

Is there a way this through a custom trigger using powershell? so anytime the ticket is created this data could be copied from one field to the other?
