Hi Umang,
in case you are using WDJ (it looks like that from your screenshot) you would have to go for modification via NWDI/NWDS with quite a bit of effort. Since there is no technical benefit (at least I see none) in your requirement, but only a slight improvement of usability I would try to convince your cleitn to discard this requirement.
Even if this was WDA I personally would not want to implement what you describe, because the Viewcontainer used for the receipts is very complex and prone to failure when enhanced (I can't prove this, it's merely my personal experience).
Cheers, Lukas
