template question for pages w/ the sidebar

[Mutt]

the advertisements with template edits thread is closed so I guess I'll ask here. I have a 720x90 banner spot I put in "ad_below_top_breadcrumb" whihc works fine on most pages BUT when there's a sidebar it's too big & needs to be a 468x60. I handle it w/ a simple if / else listing all the pages that have a sidebar in the array.

<xen:if is="in_array({$contentTemplate}, array('forum_list','EWRmedio_Media','EWRmedio_MediaView','member_list','news_feed_page_global','conversation_view'))">
 
    <xen:comment>468 x 60 AD</xen:comment>
    --- 468 x 60 ad code --- 
 
<xen:else />
 
    <xen:comment>728 x 90 AD</xen:comment>
    --- 728 x 90 ad code --- 
 
</xen:if>

problem is, I've missed a bunch. I notice them a little at a time. I'm going to go thru & look for more right now but my question is, is there a way to setup the if so it's just looking for if <xen:sidebar> exists? something like

<xen:if is="$sidebar">
 
    <xen:comment>468 x 60 AD</xen:comment>
    --- 468 x 60 ad code --- 
 
<xen:else />
 
    <xen:comment>728 x 90 AD</xen:comment>
    --- 728 x 90 ad code --- 
 
</xen:if>
