[Plugin: WooCommerce] The configuration and specification variants

Welcome!
I have a problem when creating variants of the product, which is the ticket. There are certain attributes – the beginning and end of the travel the route, time of departure, but the time of departure are different. Is this possibility to the product page on the choice of a specific locality (start of the route), display them on the list only user-specified time of departure? Currently, when a customer chooses to page beginning and destination of this journey by choosing from a list of time it displays all the options of hours, and I would like to list the only 6 of which are set in the variants on this route. Is this possible?
Greetings to all

Sorry for my english…
