Execute Script command

[Rob Lewis]

I know the manual entry for Execute Script says it works with Global Scripts. Is there any chance that with the recent reworking it can be used to call a handler in a unit script? 

Currently my Global Script has 
    execute script (thisScript) in 30

Could I put a handler in a unit ON script and say
    execute script (thisScript) handler “thisHandler” in 30
?

(I’m trying to move my PID Controller from a Global Script into a Unit.) 

On a separate issue, I was wondering if there is any significant CPU overhead in the Get Unit Property and Set Unit Property commands, as opposed to simply using properties in a script. 

Thanks.
