Door open announement

Currently i have "door open" annopuncements for my shed doors announced via an Amazon echo device in my living room.However i also have another echo device in a room upstaris where i have my pc, i would like any announcements of open doors played through the upstairs device as well as the device in my living room.I can see how to choose either echo device but i can see no way of having both devices announce "door open" at the same time.Anyone know if this is possible ?Thanks.
