Would like to use ClientAreaPageContact hook to load info for form fields from user signed in to the client portal

[TBroMEM]

Although the Contact.php has breadcrumb of Pre-Sales Contact Us, we are considering it more of an entry point for billing inquiries, but it would be more beneficial if it could default some values based on the signed-in user.

Name - preload with the users name
Email Address - preload with the users email address
Subject - preload with 'Billing inquiry from {client name} | {user name}

Message:
Client Id: {client id}
Client Name: {client name}

Etc.


Is this even possible?
