WooCommerce Subscriptions

It is very disgusting to see that the subscription is not suitable for physical product with requirement of one time shipping and free trial. Currently, if we use free trial or synchronisation to a fixed date, the one time shipping option is getting disabled and this preventing us to use for physical product which needs one time shipping and free trial and synchronisation. Can you please develop this basic feature in woocommerce subscription so that it can be used in physical product cases with one time shipping and free trial and synchronisation
