Add Trailing Slash Url Rewrite

Questions
1

I have found a rule for removing a trailing slash

<add name="noendslash" 
            virtualUrl="^(.*)/$" 
            rewriteUrlParameter="IncludeQueryStringForRewrite" 
            redirect="Application"
            destinationUrl="~$1"
            ignoreCase="true" />

 

but is there one for adding a trailing slash. My client wants it for "SEO" purposes?

Thanks

Simon
