Hi @ajay - to effectively get help in this forum, it’d be great if you could be a bit more specific with the actual problem. Now you just link to the example and request a solution to add multiple subjects: That’s a lot of work for users of the forum to dig into your problem, trying to figure out how to help you.
You can make answering to your post easier by being more concrete, and by sharing a reproducible code snippet of how far you got and where errors occur.
That’ll increase your likelihood to receive an answer.
If you have solved your problem in the meantime, please post your solution as a reply and mark your reply as the solution to this thread. Thanks!
