Increment Shift Start Flag by 1 per User

[Anonymous]

Good afterNoon,

I need some advice and help amending the following DAX code.  Which flags a 1 for When a new shift starts for every User (UserIndex).  I would like to however increment the flag by 1. The Image shows there are four rows of data in this snippet that have the flag of 1 , I want them to increment to say 1 , 2 , 3 , 4 etc... 

Shift Start Flag =

VAR A =

MAXX(

FILTER(

'Shifts',

Shifts[UserIndex] = EARLIER('Shifts'[UserIndex]) &&

Shifts[SharedEndDateTime] = EARLIER('Shifts'[SharedStartDateTime])

),

'Shifts'[Shift]

// 1

)

Return

if(A=0,1,0)

Thansk for help in advance

@Anonymous , new column. Using the flag you created

Shift Start count =
Countx(
FILTER(
'Shifts',
Shifts[UserIndex] = EARLIER('Shifts'[UserIndex]) && [Shift Start Flag] = 1
Shifts[SharedEndDateTime] <= EARLIER('Shifts'[SharedStartDateTime])
),
'Shifts'[Shift]
)
