Two companies on one smartsheet. How to divide?



I use smartsheet for several 4-5 years right now. During this time I set up two companies which scaled well. I have 2 issues:

  1. I would like to move several smartsheet to another accoun or i would like to have two seperate invoices for choosen users. How to do it?
  2. Is it possible to change my smartsheet type to EU (Im based in EU)?
