In theory, the `InternalSession.SESSION` [`ThreadLocal`](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/ThreadLocal.html) would be populated if you’re running a project script from a Perspective thread; so something like this _might_ work:

```python
from com.inductiveautomation.perspective.gateway.session import InternalSession

session = InternalSession.SESSION.get()

if session is not None:
	system.perspective.print(session.custom.something)

```
