Cloning select channels in a server to avoid message download overload

[diliprk]

Hi, I tried cloning all the channels from this https://discord.com/channels/1031673556586741830 goes by the name of PepeThugLife's Casino (Join his discord from this link - https://linktr.ee/pepethuglife ) . It has ~ 50+ channels with lots of message history, so when I ran the command cp!clone live_update=true clone_message=true real_time_messages=true process_new_messages=true in the general-chat of the channel , the discord-server-copy started recreating a complete cloned copy of the source server. Though it created the names, roles, icons of the channels the past message history did not appear, probably because of too many messages to download. Recent messages that were posted after the server channel has been cloned also appeared, but not all the past historical messages.

My question, how do I restrict the discord-server-copy to only download the past message history for select channels? Can't see something like this in the config.json options?
