Communications-Messages-Post LP Completion Automated Message

Summary

Customize a message to be sent 60 days after an LP completion to take a survey (External link)

Content

Hi all - We would like to create a 'message' that would have a trigger of 60 days PAST a LP completion date.  The message would contain a link to an external SharePoint site where they would take the survey.  Does anyone know how that could be accomplished?

I thought I could 'copy' the LP completed message and add a trigger...nope....no triggers available....I looked at all other LP messages and could not find something.

As always, I appreciate any feedback/guidance.
