Is there a way to modify the pre-filled data in the Express object from the front-end form?

Using Concrete / Help

the version of Concrete 9.2.0
the version of PHP 8.2.5

Is there a way to modify the pre-filled data in the Express object from the front-end form?
Is modification only possible from the administration screen?

Are there any add-ons or themes available that allow modification from the front-end screen?

I would be grateful to you for any assistance.

Can you give me an example of what you’re trying to do? That might help me understand the problem better. Thanks!
