How to support a "Save draft" to a wizard approach when the user takes a long time to complete a step?

I have simple user workflow, in which the User has to complete the process sequentially. But the step 2 might take a day or more to get completed.

In the Current UI, If user decides to complete the process later, they can click "save" to skip the process and they will be taken to summary page. User can save the whole process as draft. When the user returns back to edit, There will be no wizard approach. They can modify each step by individually selecting the process steps from the summary.

Is the approach is intuitive? Is there any alternate patterns to handle save draft in a wizard approach?
