Is it possible to have a vector input to a Simulink if-statement block?

I am working on vectorising my model and I got stuck when I tried to vectorise the if-statement block. I wonder if it is possible to do it in Simulink. I know that it will work if I get each singal individually and apply them to multiple of if-statement blocks, but this is not what I want to do. Any suggestions will be greatly appreciated!

This is what I want to do and the error that I get:

You can only apply scalars to the if port of action subsystems. Consider your example where you test:

out1_of_if_block = u1 == [1 2] = [1 0]

What do you expect the If Action Subsystem2 to do when [1 0] is applied to the action port?

Perhaps inside of the 'If' block, you would want to do something more like this:

u1(1) == 1

Thank you so much for your answer. I wanted to check each element of the input vector with the scalar inside the if statement and obtain a vector output based on the result of this check. As you also stated, it seems I cannot do what I want with the if statements. I solved my problem with using the basic logical operators instead, which accept vector inputs.

Can u please show me how u did it? I'm having the same problem ):
