Post function

Post functions on the Cloud version of Workflow Enhancer for Jira work differently than on DC, as Atlassian is currently not offering the possibility to call other post functions within post functions, see https://ecosystem.atlassian.net/browse/FRGE-1230. Please feel free to vote and/or comment the linked issue in order to help us being able to provide this functionality also for the Cloud version of Workflow Enhancer for Jira.
