Is it possible to get all the values of a repeating custom field (for a specific post) and add them "as one" to a different custom field? For example, repeating field is "wpcf-custom-field", post has 5 instances with values "red", "yellow", "green", "blue" & "white", the meta value of the other field (say "wpcf-custom-field-merged") would then be "red yellow green blue white" or better still "red, yellow, green, blue, white".

Thanks

Hello,

There isn't such kind of built-in feature, it needs custom codes, for example, you can get the custom field "wpcf-custom-field" value as an array:
https://codex.wordpress.org/Function_Reference/get_post_meta
$single
(bool) (Optional) If true, returns only the first value for the specified meta key. This parameter has no effect if $key is not specified.

Then use above value to update another field value as what you want:

Do you mean like this?

add_action('cred_save_data', 'save_data_form_1974',10,2);
function save_data_form_1974($post_id, $form_data) {
    
    if ($form_data['id']==1974) {
        
        $rfg_all_values = get_post_meta($post_id,  'wpcf-custom-field',  false);        
        update_post_meta($post_id,  'wpcf-custom-field-merged',  $rfg_all_values);
	    }
}

I assume you are using Toolset Forms plugin to create the new post, you need to turn the PHP array into a string, for example:

add_action('cred_save_data_1974', 'save_data_form_1974',10,2);
function save_data_form_1974($post_id, $form_data) {
	$arr = get_post_meta($post_id,  'wpcf-custom-field',  false);
	$str = implode(', ', $arr);
	update_post_meta($post_id,  'wpcf-custom-field-merged',  $str);
}
