As you've only been doing it a couple of days, you won't lose much if you swap to RM2K3 - solely for the reason that you can do the things in it that you can't in RMXP.

Otherwise, you could have the first event end with turning a switch on, whilst the second switch (as a parallel process) contains a conditional branch that has the main event in the "If:" branch - if switch[0001] = ON.
