How does Pattr persist state between sessions in a Standalone

Greetings,

Can someone provide some insight into how Pattr saves state in a standalone?

I would like to create a standalone that saves state when the patch closes and recalls that state the next time the patch is opened.

When buildling the patch, I noticed, that in order for pattr to save it's current state you need to save the patch. If I save the patch, the next time I open it, pattr will restore to the state it was in when I saved it. This makes sense. I can see the values are actually written and saved into the patch JSON.

But how does this work in a standalone? The user cannot save the patch. And I wouldn't want them to have to anyway.

So how does pattr persist state between sessions in a standalone? So far, what i've observed is it doesn't. When I launch the patch, pattr restores the state that was saved when I created the standalone. Even after I've made changes to that state and closed the standalone.

Special note: I'm not actually using pattr objects in my use case, I'm using an SDK External with a "value" attribute. But according to my reading, this is handled using the same system as pattr, so the question should still apply.

Thanks for any input!
