Variable accessor?

Is there any chance we can get something like variable accessors from C#? AT least the ‘set’ accessor. It would be very useful for building blueprint actors to have something that lets you run blueprint nodes when a variable is changed during runtime

I want to let level designers have access to a variable when the level object gets built, but afterwards I need them to run a function call whenever they try to change it - with accessors I wouldn’t have to do that.
