Join multiple Chunks or Embeddings Env?

Hi team. Simple question about embeedings. I have 500 chunks under Pinecone Environment A. And a chatbot with that Environment A set properly. Now I need a second Chatbot B, with same 500 chunks present on Environment A + 1000 new additional chunks. How can I solve this situation without requiring to save again 500 chunks into new Environment B?

• Is there possibility to set 500 chunks into 2 different Environment A & B?
• Or is there possibility to set 2 Environments to a chatbot? A with 500 chunks + B with 1000 chunks

Many thanks.
