Can I apply for a Smart Visa S with a partner and switch from a tourist or education visa?

Hello all,

I have a few questions.

I plan on applying for the Smart Visa S. How does it work if I plan on going with a partner? I see on the form there is a place to put down "Key persons of organization" but there is no where to put down their personal information. Or is the Smart S Visa only applicable for a single person?

Also, is it possible to go on a tourist or education visa prior, and then switch over to the Smart S visa upon approval?

Thanks in advance.
