Creating a gant chart using a matrix and how to create an event rank

[CastroRibeiro]

I'm creating a gant chart using a matrix, because I need a certain customization...

I'm trying to find a solution for when events have a start and end date on the same day, that is, when they are conflicting

I thought of creating a ranking of the events that are most important.

In my case, if I were to create a rank based on the switch function (code below), it would look like this, in order of importance:

First: 1.8 12.11
Second: 2, 3, 10
Third:6
Room:3
Fifth:5,9,13

Today I use conditional customization to fill the cells with colors

Is this the best idea? Is there any better and how can I do it?

My code:

Periodo = 
var _startDate = 
    CALCULATE(
        MIN('TBL_DISPONIBILIDADE_FROTA_AEREA'[MARCO_INICIAL]),
        ALL(CUSTOM_CALENDARIO)
    )
var _endDate = 
    CALCULATE(
        MAX('TBL_DISPONIBILIDADE_FROTA_AEREA'[MARCO_FINAL]),
        ALL(CUSTOM_CALENDARIO)
    )
var _period = 
    MIN(CUSTOM_CALENDARIO[Data])>= _startDate
    && MAX(CUSTOM_CALENDARIO[Data]) <= _endDate

var _status = 
    CALCULATE(
        MAX(TBL_DISPONIBILIDADE_FROTA_AEREA[STATUS]),
         ALL(CUSTOM_CALENDARIO)
    )


RETURN
SWITCH(
    TRUE()
    ,_period && _status = "INDISPONÍVEL",1
    ,_period && _status = "PREVISTO",2
    ,_period &&  _status = "PRONTO COMUNICADO",3
    ,_period &&  _status = "PRONTO NÃO VALIDADO",4
    ,_period &&  _status = "ENCERRADO",5
    ,_period && _status = "FRANQUIA SOLICITADA",6
    ,_period && _status = "FRANQUIA AUTORIZADA",7
    ,_period && _status = "FRANQUIA EM CURSO",8
    ,_period && _status = "FRANQUIA ENCERRADA",9
    ,_period && _status = "ACC AGENDADO",10
    ,_period && _status = "ACC EM CURSO",11
    ,_period && _status = "ACC ENCERRADO",12 
    )
