The ability to create multiple listings for all of the multistores simultaneously for the same stockitem. At the moment it is not possible to list the same item on multiple multistore channels, you need to have multiple titles per channels added or manually edit the SKU on the template in LinnLive before the creation.

Sorry for my ignorance but dont you just list in Magentos default store view and then just add the set of new products in bulk to the other shops?
