splitting pdfs in workflow

I want to split and count pages in a pdf:

How to proceed in workflow?

Folder Capture PDF -> Create Metadata -> Metadata Level Creation (Splits by document level, begin when region contains specific first page data) -> 2 branches with metadata filter (pagecount <12, pagecount >=12)

this works, metadata is correct, page counts can be accessed (and stored in a variable).

But then how can I create the split pdf in each branch according to the metadata?

PDF Splitter action.

Split method = Split PDF file based on Metadata.
