Reference pattern

Hello everyone,

I'm having a problem.

I have an assembly where I have put a few guide pillars. The first one by constraint to an axis system, and the following by pattern.

Now I want to create the hole for the clamps of the guide pillar. The first clamp was also constrained for position, and the followings, where patterned as well.

Now, for create the hole in the plate, to fix the clamp, I made a reference, to first clamp, of the first guide pillar

Now when I create the reference pattern, only the pattern of the guide pillars is made.

The pattern of the clamps isn't created...

So my question is, how to create the holes of all clamps, without creating one by one. And keeping in mind that later on the design i might change the number of clamps, from 2 to 4 for example. And the pattern be recognized and properly updated.

Any idea? what I'm missing.
