How to select 100 items from a list

[TalkNet_TechnoS]

I need to select the first 100 items from a list generated from several SELECT lists added.

LIST((SELECT(Destinatarios Fijos[_RowNumber],true)+
SELECT(Destinatarios Importados 1[_RowNumber],true)+
SELECT(Destinatarios Importados 2[_RowNumber],true)+
SELECT(Destinatarios Importados 3[_RowNumber],true)+
SELECT(Destinatarios Importados 4[_RowNumber],true))-
SPLIT(SELECT(Envíos[Destinatarios],[Campaña Id]=[_THISROW].[Campaña Id])))

I understand that I must do it with FILTER () and with INDEX () but I can’t find a way.
Any guidance?
