custom task list in sharepoint 2013 sharepoint hosted app workflow

Hi,

I am creating list based workflow in sharepoint hosted app. which creates automatically two list (Task and History). And both of the list are just the instance (I mean list definition is not available for both). 

I am using client side rendering for to customize the view of list. But in this situation i do not have list definition where i can keep my JSlink. 

Is that possible to use a custom task list instead of autometically created task list ?.

Thanks and Regards:
