Shortcode Form For Specific User ID

I would like to setup the shortcode form to pull to get a query string of the User ID and use that

http://example.com/update-customer-info/?id=3

I already use use_current_user=false so that it doesnt use current info, I would like to avoid user accounts, as customer’s do not need or want to signup. I do want to be able to send an email where a customer can update his profile though. I will probably encrypt the user ID in the query string, or make it expire. But this is the basic example.

Is there somewhere in the code / plugin that I can replace the current_user from use_current_user=true with the user that i am specifying by ID?

Thanks
