Feature Request : Run command(s) automatically after login

[Swaphelaer]

I'd like to be able to run a command automatically right after logging in.
With CLI ssh this is accomplished by adding a command between quotes at the end.
Example :
ssh @ "sudo su - "
name is my name (remote account) and user is the remote user I need to switch to.
In this example I don't know the password of but is in the sudoers-file.

But can imagine there are lots of other usages for this request.
