Multiple posts generated by one form

I need to create a form capable of creating multiple posts (each in their own category). I found something about gform_post_submission, but it's not clear to me whether this means what I want is possible. Can you help me further along?

That's a shame. Time and my customer's budget will not allow me to delve into creating it all myself.. What happened to the Advanced Post Creation add-on that was being built a few years back?

Is there another way? Is it possible somehow to create conditional fields based on values of a different form?

Somebody managed to get it work? I think that it is very interesting feature to create for example a simple post of 30 fields Curricullum Vitae of some Job Applicant and use 5 fields to automaticaly create a new user for custom post type "mailing_list. "
Another example is to create club custom post type "EVENT" with club location fields and then in the background create a new custom post type "CLUB" info.
Is it hard to create in the background e new custom post type CLUB entry with some 3-5 fields one per line?
Can you provide an example as you have provided here: ?

Very amateur example below:

<?php
add_action("gform_after_submission", "set_post_content", 10, 2);
function set_post_content($entry, $form){

    //getting post
    $post = get_post($entry["post_id"]);

    //changing post content
    $post->post_content = "Club Info: "<br/> " . $entry[1] . " <br/>
 "<br/> " . $entry[2] . " <br/>
 "<br/> " . $entry[3] . " <br/>
 "<br/> " . $entry[4] . " <br/>
 "<br/> " . $entry[5] . " <br/>

    //updating post
    wp_update_post($post);
}
?>
