Gravityview - Show payment status of another form - gravity-forms-plugin

Question

I currently have Gravityview view which is getting the source from form A. However, I want to show if the current user has made a payment on form B. Obviously this can be fetched from the {payment_status} merge tag of form B. But How can I pull the data of form B onto the Gravity view custom content field of form A?
I've looked at the gform_entry_id_pre_save_lead hook but I think there's a better way. Thanks for your help in advance..
add_filter( 'gform_entry_id_pre_save_lead', 'my_update_entry_on_form_submission', 10, 2 );
function my_update_entry_on_form_submission( $entry_id, $form ) {
$update_entry_id = rgpost( 'my_update_entry_id' );
return $update_entry_id ? $update_entry_id : $entry_id;
}

You can either use the Gravityview Multiple Forms Add-on or you can try adding the following code to your functions.php:
function gf_check_form($atts = array()) {
$details = shortcode_atts( array(
'form_id' => "",
'user' => ""
), $atts );
$form_id = $details['form_id'];
$search_criteria = array(
'status' => 'active',
'field_filters' => array(
'mode' => 'all',
array(
'key' => 'created_by',
'operator'=> 'is',
'value' => $details['user']
)
)
);
$entries = GFAPI::get_entries( $form_id, $search_criteria);
foreach($entries as $entry){
$paid .= 'Paid on '.date("F d, Y", strtotime($entry['date_created'])).'<br><br>';
}
return $paid;
}
add_shortcode( 'check_form', 'gf_check_form' );
You can then add the following shortcode to your Gravityview in a custom content field:
[check_form form_id="Add the form ID of form B here" user="{created_by:ID}"]
