Formbuilder fieldLabel postfix/prefix [feature request?]

Hi PEARs, I'm using this inside a DO: var $fb_linkDisplayFields = array('name', 'price', 'costcategory_id'); var $fb_linkDisplayLevel = 2; I want to append an Euro symbol to the 'price', so It can be easy identified in the select field being generated. Is this possible? I'm trying to do it by using this: function postGenerateForm(&$form, &$fb) {

    $costvariable_id = &$form->getElement('costvariable_id');
    foreach ($costvariable_id->_options as $opt) {
        // Do some kind of replacement here
    }

} Any ideas? Thanks, Rodrigo.
