No, but you can use landscape to run commands on the box. You could (for example) run whatever you wanted to run via ssh, but as a script.
Another option would be to setup a reverse SSH tunnel via that script system.
So you could create a script to run on the landscape managed host which ssh'ed back to your home machine or some other publicly accessible IP:-
ssh -R2222:localhost:22 email@example.com
You'd need an ssh key to already be generated without a pass-phrase on the remote machine and place the public part on 'homeserver' in ~/.ssh/authorized_keys as a pre-requisite to doing this.
Once that ssh tunnel is setup, you should be able to (on homeserver.example.com):-
ssh -P 2222 username@localhost
This will redirect ssh (on port 2222) from homeserver.example.com to port 22 on the remote host.
