Angular ng-content n first element

Question

Hi I'm trying to split the content of a component in two parts and I can't seems to make it work. I know that I can user ng-content with the attribute select but I don't know if it's possible to select a number of element with it.

I have this code:

<component-x>
  <div>1</div>
  <div>2</div>
  <div>3</div>
  <div>4</div>
  <div>5</div>
</component-x>

Inside my component-x, I want it to be like this:

<div class="x">
  <div class="y">
    <ng-content></ng-content>
  </div>
  <div class="z">
    <ng-content select="{{lastXDivs}}"></ng-content>
  </div>
</div>

Where lastXDivs equals a number of children.

My result would be like this:

<div class="x">
  <div class="y">
    <div>1</div>
    <div>2</div>
    <div>3</div>
  </div>
  <div class="z">
    <div>4</div>
    <div>5</div>
  </div>
</div>

Is there a way to achieve this?

Note that in my case, the content of divs 1 to 5 are dynamic.

Thanks
