Can I trigger a junction to a set state

Just wondering if it is possible to place a trigger down well before a junction so it makes it change we ll before you get to it's junction signal?

Have tried different things but to date have had no luck so thought I would ask on here

Wait For > Trigger > [whichever train]
- Junction Rule

That rule is one of the clever things of the simulator. My only problem is that when I set it, it slows down all the other menus, I mean the response time to show when you select anything, commands, etc. In surveyor or drive. Am I the only one with this problem?

All my menus are horrendously slow. I can click on a driver command arrow and count 3 seconds before anything shows up. Probably has something to do with having lots of switches and trackside objects on your route, although I've always thought this crap performance to be typical of Trainz itself rather than due to any particular rule.
