Hi Dasu,
There are two things that you can try to get your desired out put.
1. Redesign the work which you deploy into your extensions folder and add what you need to it. This will need you to disable and undeploy the OOTB workflow.
2. You can edit the OOTB workflow to add what you need.
All these step are not necessarily recommended as with new release and upgrade; you custom changes my clash or entirely be overridden.
You will have to decide on what suits you best, I would suggest build your own custom workflow as those that come OOTB were designed with a certain idea in mind, which is to be generic; which is why there are only a handful of them.
