As Usual, great plugin from best payment gateway in India

Hello and I have a couple of questions to avail a bit of extended functionality on the given page link.

1) Is it possible to use multiple [RZP] shortcodes on one page/post?
2) What can be the alternate of the page_id (which is currently used) used as reference to relate amount/name/description of the product to the payment parameters to generate the order, in case of point no. 1?

I can customize the plugin and add pull requests to the project, but I just need initial suggestions.

Thanks
