ok, if you know a little coding language it's not that hard, try this:
If you read the Cheatwiki on how to do the coordinates hack, you'll see that you can 'read' the value you need from the minimap (left corner), if you go to the portal to go to ruina station and press 'M' you would see X:30* Y:189*, this are not the values you need, add 2 zero's behind every number. x: 3000 Y:18900, that are the numbers you need.
Now program 1 hotkey to change both the X and the Y-addresses into those values, then it would spawn you in front of the portal.
I hope this answers your question.
*these numbers are just as example
