You can. You want the command "Set Warp Transit orders", under "settings orders", default hotkey shift-,

EDIT: little note on that- you'll notice the same as previous button. You CAN send all your ships through at once- but they might collide inside the warp point and explode. By default there's a 10% chance of that happening, so if you send 100 ships through at once, expect to get 80-90 out the other end..
