Thanks for posting here and welcome to the community! 
Unfortunately at the moment it is not possible to pass in dynamic data in the form description. The Resume on Form Submitted option is built is a wrapper for the n8n Form Trigger Node, which cannot take any data input by design.
But feel free to vote on this feature request here:

One feature request we have recently put into reality is this one:
https://community.n8n.io/t/n8n-form-trigger-url-parameter/33407/
You can populate the fields via query params.
We will be updating our docs soon to reflect these new features.
as you can see, we appreciate our user feature requests and are constantly working on implementing those as much as possible
