You can make a Post Function in the workflow which can transition the status for you.

1. Go to your workflow
2. Click edit and select the "Create" transition and click on Post Functions
3. Add new Post Function
4. Select Script Post-Function [ScriptRunner] 
5. Then select Fast-track transition an issue

If you want it to work for "In Progress" Status, you should set conditions as:

issue.issueType.name == 'Sub-task' &&
issue.parentObject.getStatus().getSimpleStatus().getName() == "In Progress"

and then select the relevant action for that status, in the simple example it would be "Start Progress" action.

You can make a post function for each status you would like it to work for.

Any other values you would like to copy can be added in the "additional actions"
