Hi Navin,
Absolutely agree with Ronen with the point that similar scenario is present in WS17900004 where the link is passed to subsequent send mail step via binding.
Apart from that if you want reusablity and flexibility and have more time to invest , then can go for a custom task tailor made to handle the scenario.How it is implemented will ensure the re usability in other workflows.
