Select gpts like plugins / multiple gpt convo

There needs to be a way for you to select multiple gpts or change out your created GPTs in a conversation to include the results and understanding from the specific gpts. There also needs to eventually be multiple gpts able to talk and conversate with one another sort of like autogens multiple agent conversations.

There also needs to be the ability to paste in entire project folders to chat gpt (some projects you can submit the files, but the GPT does not understand full context because no helper files were analyzed.)
