How to register a global property through plugin config

[coreybruyere]

I'm using the analytics plugin with mixpanel. Is there a way to pass a custom property to mixpanel from the initialized plugin ? Example: Passing a property of site and value of blog in one place within plugin instantiation so that all events (page, track, identity) pass that custom property to mixpanel?

export const analytics = Analytics({
    app: 'website',
    debug: process.env.NODE_ENV !== 'production',
    plugins: IS_BROWSER ? [
        mixpanelPlugin({
            token: TOKEN,
        }),
    ] : []
});
