Yes there is a trainer that lets you do this - The Beast Trainer at
http://coastergrotto.zzn.com.
At the moment it sets all the rides to preset values (excitment 20.00, intensity 5.00, and nausea 0.0), but in future versions this may change to let you select the values for each ride.
NOTE: The trainer only works for the UK version of the LL, but a US version will be coming out in a few weeks with lots of features never seen on a trainer before.
