Inbetween Chat Sync Feature

I often chat in chatgpt to brainstorm stories and ideas, but the problem is my chat gets to big and I copy paste a text section from a chat to another chat telling it to keep up the datas clean and in order. It would be a help if you add a sync option in 3 dots above chats. Sync> which chat - (1) (2) (3)> choose and Synced. Then I can directly tell gpt in another chat to take first , fifth, 11th, 16th , 20th text section and put them into a new order.
