Different code wrapping for each widget

Hello, I cannot use the Array “Before” “After” to dress my widgets… I have real random and different coding for each widget.

For example:

Pages: Will be wrapped with have 4 divs

Blogroll: Will be wrapped with 2 divs

Is there a way to dress the “before” “after” for each WIDGET INDIVIDUALLY, instead of this array code from functions.php?

<?php
if ( function_exists('register_sidebar') )
    register_sidebar(array(
        'before_widget' => '<div id="right-red"><div id="right-red-top">',
        'after_widget' => '<div id="right-red-bottom"></div></div>',
        'before_title' => '<div id="right-red-title">',
        'after_title' => '</div><div id="right-red-text">%1$s</div></div>
<ul>',
    ));
