Pattern a Split or Alternatives

So, I have a part I want to split (and I explicitly want multiple parts, not a surface split). However I want to split it into a lot of segments, the only way I found to do it was to pattern the thing I am splitting with (in this case a plane) then create a whole lot of individual splits, like this:
This is obviously pretty painful, in this case setting up 21 splits. The first thing I tried to do was pattern the split feature however this does not work. The face split allows multiple entities for splitting but the part split only allows a single one.
Is there an obvious way to achieve this that I am missing? Note that I specifically want to start with the completed model and split it in this case, I am not trying to find a way to model it already split up.

In this particular case, try creating a single surface that zig zags along the offset planes. It will look like a step function.

I was also able to pattern the split using a feature pattern. You just have to remember to pattern any ancestors of the feature being patterned as well - the offset plane in this case.

Cool idea, thanks!0

I did a couple posts one after the other. Make sure you take a look at the second one, since it's probably a better way to do it

Ah, that would be the issue then. In my case I had 4 offset planes and I had forgotten to select these I think.mahir said:I was also able to pattern the split using a feature pattern.

Nice job @mahir
Despite the neat workaround I still think it's valid to request a split command that takes multiple inputs.
If there isn't an existing one I'll put in an IR.
