Thanks @pavan3753 for your suggestions. I had explored these options but the problem with first approach you have mentioned is it will be difficult if we have many work level properties we want to use say around 20 properties. And in future if we want to use more properties then every time we will have to modify the step where we are calling the data page to add the parameter.

Problem with defining pyWorkPage is when the case is created using an agent, page context might be some temp page and anyways it's not a good practice to use pyWorkPage.
