Solidworks NEW Feature Required: Thicken Multiple Surfaes at once

in SolidWorks when we use surface thicken, we have to select "a" surface, that's tragic when you have many surfaces to thicken and you cant knit them, you have to use thicken again and again,

if they could add such feature in 2014 version or in 2013 service packs it'll be fun! thanks!
