No.

That's a client implementation issue.  With OpenSSH we
have an experimental SOCKS4 interface for dynamic portforwarding
(see -D in ssh(1)), so this is not a protocol issue.

With SSH protocol v2 you can request server-to-client
or client-to-server forwardings at any time, you don't
need to setup forwardings in advance.
