Basically i would want to add catalyst to some TFC+ NEI recipes, problem is it already has some subcategory in the handler
Here an example where when you U on a leather, it show you all leather knapping recipes

My problem is when i try to add a catalyst with the leather, it just override this function and make the U just show all knapping recipes instead of only the leather ones.
Not sure if this could be just a compat made with specifically for TFC+ NEI or it could be an extra option in the catalysts csv file
Hope you guys take this suggestion

Holding ctrl key will skip search for catalysts. Or override method getUsageAndCatalystHandler and modify it on TFC side.
