I have following command in my .htaccess

    RewriteCond %{HTTP_HOST} ^(www\.)?([a-z0-9-]+)\.example\.com [NC]
    RewriteRule ^(.*?)-([a-z]+) %2/$1.$2 [L]
    RewriteRule ^(.*?)-([0-9]+)([a-z]) %2/$1$3.$2 [L]

%2 is not working in second and later lines. Can I define any variable for %2 and use it in all RewriteRule commands? Following command works

     RewriteCond %{HTTP_HOST} ^(www\.)?([a-z0-9-]+)\.example\.com [NC]
     RewriteRule ^(.*?)-([a-z]+) %2/$1.$2 [L]
     RewriteCond %{HTTP_HOST} ^(www\.)?([a-z0-9-]+)\.example\.com [NC]
     RewriteRule ^(.*?)-([0-9]+)([a-z]) %2/$1$3.$2 [L]

But I want use %2 for multiple rule line without duplicating condition.
