I read a short while ago (when I was looking for the same functionality myself) that there was no way to have Logos 4 open a custom layout with chosen verse(s) by typing the verse(s) into the 'Go' box.
To do it you would have to either use 'Go' to load the standard layout and then customise it each time, or have a pre-saved layout you manually load and then type the verse(s) in each of the entry fields.
I have used Applescript to make an automated solution for this. You can see it in action in this screencast.

To achieve this — because Logos 4 Mac does not support full OS X object scripting — I tricked it using UI (user interface) scripting which essentially acts as an automated user. It works (as you can see in the screencast) the only requirement is that the script is specific to the Logos 4 Mac screen layout. I have three panes: PG & EG; Commentaries; Bibles. Also there needs to be a custom saved layout called "My Layout".
By changing settings affected by layout of resources the script can be adjusted to suit.
Not sure how much interest there would be from people for this - so I decided to put it up as demo screencast to gauge interest first.
If you are interested drop a reply to this posting and I can make it available (free naturally) to people.
