How to rollback/goto any previous step in custom workflow model programatically? [AEM6.4]

Question

Hi,I'm using AEM6.4 for this project and there's a scenario in the Workflow where on the particular condition I need to 'Go back to one of the previous workflow steps?'Say(refer image below): When the action fails on 'Step D' the control/workflow must be set again to 'Step A' and start again from that step.I'm new to AEM & not sure if that's even possible but that's what is the requirement?I saw a brief note on 'GoTo' statements for AEM 6.4 documentation on workflows but that's it just 2-3 lines about it. (not very helpful)But unfortunately couldn't find any reference doc or example regarding the same. Or in other words:There's already Rollback(to any previous workflow step) functionality available in AEM (AEM6.4 atleast) via UI whenever a workflow step fails (refer image below). I just want to achieve this programmatically within the custom workflow process class.Any help regarding this is appreciated.-Thanks

Hello,

You can use the Route API to advance the Workflow in variable available directions.

To fetch all available Routes use:

List<Route> routes = workflowSession.getRoutes(workItem, false);

Then based on name/id of the route, you can advance the workflow
