Auto-fill form plain text field

On my home page I wanted to upfront the x2 most important text fields for the different user types that may be visiting the page: make a claim or rent a car. I want their form submissions from the home page to appear pre-populated into the actual form on the designated page so that they do not have to re-enter the field. If this is possible please let me know?

Thank you very much, any help is appreciated.

Here is my site Read-Only: [Webflow - Omega Car Rentals]

Thank you so much @spirelli for sending through these links. Im very very unsure of how to achieve my desired result. Is there anyway someone can provide me with clear directions on how to achieve this? Thanks again!
