Is there some way with GroovyScripting (ScriptRunner) add your your own ChangeHistoryItems to activity-history section.
I've tried to search for ChangeHistoryManager and classes that it produces ChangeHistory, ChangeHistoryItem but it haven't methods for updating/adding new history items (only methods for finding and removing.)
Some examples from ChangeLogUtils
If not, some way to access db from scriptrunner and couple of classes connected to ChangeHistory DAL layer.
