Split table in multiple ranges with Table.PositionOf and Occurrence.All

[ooptennoort]

I need to split a table into a range everytime Table.PositionOf finds the "Marker word". It works when using only 1 Occurence (.First or .Last) but .All produces more than 1 number in the list and Table.Range cannot deal with this.

= Table.Range(Source,(Table.PositionOf(Source,[Column1="Marker word"],Occurrence.All,"Column1")),5)

How do I get this to work? In other words, how do I get Table.Range to work on each number in a list of more than one number???? Or rather, how do I "convert a value of type List to type Number" in this context i.e. producing multiple ranges (ideally appended)?

Somehow a recursive function or loop (is there a difference?) would maybe work. Or perhaps a let with some variable, but I still lack M code knowlegde.

AlienSx from PBI forum came up with a very simple and elegant solution!!

positions = List.Buffer(Table.PositionOf(Source,[Column1="Marker word"],Occurrence.All,"Column1")),
ranges = Table.Combine( List.Transform(positions, each Table.Range(Source, _, 5)) )
