No, there's a section on the UEFA website when you order where you can request to be sat near someone by using their reference. Not guaranteed but did work well for last year's Europa League final in my experience.If you are going with your mates all with different points how do you buy seats together. Do you wait for the lowest point criteria to be available the buy together?
Would buy as soon as you can. Only danger is the lower points ones may not be able to get the same category when it comes to their turn to buy.
