Batch Property Update

Aug 10 at 7:31 PM
Do you know if it is possible to set an expression using the Batch Property Update feature?

For example, I am trying to do something like this:

Path:
\Package.Expressions[DisableEventHandlers]

Value:
@[System::ServerExecutionID] == 0

i.e - what this would do is disable event handlers when running in design mode.

It feels like something that could be possible (wheter in a future update or not) - if it is, does anyone know the path to get to expressions?
