Hello,

You can a prefilled link in Google forms by going to the three dot menu and clicking on Get pre-filled link button. However, what you need here is pre-filled link and assign feature, both of which are available in JotForm.

2) Fill in the fields.

3) Generate a URL.

4) Share the URL with your users.

Also, you can look at this guide:

If you want to the users can't change the prefilled fields you can set the fields "read-only" before the generating a prepopulated form. You can do this as you can see below:

You can use JotForm Mobile if your team members will visit your customers in the field. JotForm Mobile Forms allows you to build, fill out, and view forms on your mobile device. You can assign forms to certain team members so that they can have access to your forms while you remain the form owner. Moreover, you can reach out submissions from different assignees separately.
