Replace null with 0 if Header contains specific part of string

[Till__]

I want to replace null with 0 for different columns if the Header has a specific part of a string as here "costs". For example for the headers with: costs 2020 xyz, costs 2021 zy, costs 1996 hscdf

 = Table.ReplaceValue(#"Entfernte Spalten",null,0,Replacer.ReplaceValue,{"costs 2020 "})

 = Table.ReplaceValue(#"Entfernte Spalten",null,0,Replacer.ReplaceValue,{"costs 2021"})

 = Table.ReplaceValue(#"Entfernte Spalten",null,0,Replacer.ReplaceValue,{"costs 1996 hscdf})

As I have quite a lot of these columns to change manually I want to change the null with 0 for all columns if the header contains "costs". 

Thank you for your help in advance!

I found a solution myself 

= Table.ReplaceValue(#"Entfernte Spalten",null,0,Replacer.ReplaceValue,List.Select(Table.ColumnNames(#"Entfernte Spalten"), each Text.Contains(_, "one-time costs")))
