Enter at the same time Hour and Daily wage

Question

Hi friends,
in my project I had some human resources (working on different tasks), and I need to enter for them a standard rate but at the same time a daily rate (Imagine they're working abroad, so I pay their job but also a fixed rate for every day spent abroad ). 
How enter these two kinds of wages?
The resource, in the same same day, might be employed in more tasks.
I would like to avoid the duplication of the "abroad wage" if the resource is employed in two tasks in the same day.
Thank you!!

Nico,
I have yet another solution. Some months ago another user wanted to know how to make Project calculate cost based on a day rate rather than the default hourly rate. I developed a macro to do that. It puts the day rate cost into the Cost1 field. So....if
you use the normal hourly rate to cost out the job and then run the macro, you can combine the two cost totals. Herewith is the macro (it may need some tweaking for your needs):
'This macro calculates cost based on a day rate and puts it into Cost1
'   part days (e.g. 4h) are treated a full days
'   It does NOT account for a resource who works one task for 4h and then another
'   task for 4h. He/She will accrue cost for 2 full days, one on each task
'   Kosher? No, not in my mind, but that's the ways it's done in some regions
Sub DayTripper()
Dim t As Task
Dim a As Assignment
Dim r As Resource
Dim NumDa As Integer
Dim MPD As Single, PartDa As Single, PR As Single
Dim RR As String
Dim aSt As Date
MPD = ActiveProject.HoursPerDay * 60
For Each r In ActiveProject.Resources
    RR = r.PayRates(1).StandardRate
    PR = CSng(Mid(RR, 2, InStr(1, RR, "/") - 2))
    For Each a In r.Assignments
        If DateValue(a.Start) <> aSt Then
            NumDa = CInt(a.Work / MPD)
            PartDa = CDec(a.Work / MPD) - NumDa
            If PartDa > 0 Then NumDa = NumDa + 1
            a.Cost1 = NumDa * PR
            aSt = DateValue(a.Start)
        End If
    Next a
    aSt = DateValue("12:00:00 AM")
Next r
End Sub
Hope this helps.
