imapc settings for specific mailbox / namespaces

Hello,

Is it possible to use imapc for specific mailbox or namespace?

Something like this:

namespace Test {

list = no
type = private
inbox = no
hidden=no
prefix = TEST/
separator = /
location = imapc:
imapc_host = imap.example.com
imapc_password = secret
imapc_port = 143
imapc_user = user@example.com

}

or is only intended for general use as general proxy in the global configuration?
