support for subscriber creation in trigger function

[prathapbelli]

As I read we have node package support for triggering event with subscriber details which basically upsert the subscriber before triggering event. two modes

1. Ahead of Trigger
2. Inline of Trigger

to: {
      subscriberId: '<USER_IDENTIFIER>',
      email: '[email protected]',
      firstName: 'John',
      lastName: 'Doe',
    },

Can we get that Inline of Trigger functionality in python sdk
