You can select all 189 and 190 PR option in same EOI. There is no need to file separate 190 EOI in state website. Once you select 190, system gives you option to select the specific state. At this time, you can only select either one state or all. There is no option of selecting multiple states in SkillSelect. Example: If you are only interested in NSW (New south wales), then you can select only NSW. All other states will not even look at your EOI for invitation. If you select all states, your profile and points will be visible to all Australia states and they can invite you. Note that 190 visa has the condition of staying for at-least 2 years in the state after getting PR.
