Feature Request: Run Alias on Startup

[Vlek]

With the ability to write variables into userdata, it would be nice to be able to have an alias call itself when the player starts so that they do not have to remember to always do it manually. I tried writing a trigger for this, but there doesn't seem to be a decent way to have it only run once without having it hinge on something very common. Like making aliases for all of the movements that sends the movement but also checks whether one's main variables are written and calls your update script if they're not. Right now I have as much as I can under my "update" alias to try to cut down on loading.

I believe this feature would be best created as a checkbox that is selectable if a player wishes for that particular thing to be performed on startup.
