Bypass 'Begin' Button after Manager Submits PD for Approval

Summary

Manager currently needs to click on 'Begin' Button to start the Approval Process after they have Submitted the Performance Document. How can we Bypass this double clicking for managers.

We have HOD approval after Manager has completed the Manger's Evaluation.

Currently after manager clicks the "Submit" button on performance document, they have go click on "Begin" button against Approval Task to initiate the approval. This is extremely problematic as most of the time managers would forget to do this double clicking. Intuitively once they have "Submitted" it should directly go for further approvals.

Can anyone please suggest how can we bypass this additional action step requirement of clicking on "Begin" button?
