Yes, it is possible, but would take some coding to accomplish it.  The code
would be in the form, not the sub form.  You could provide two text boxes -
one for the from number and one from the to number.  The a command button to
add the records.  It might go something like this (untested air code):

Dim lngFrom as Long
Dim lngTo as Long
Dim lngCounter as Long
Dim dbf as Database
Dim rst as Recordset

   Set dbf = CurrentDb
   Set rst = CurrentDb.OpenRecordset("InvoiceTable", dbOpenDynaset)
   lngFrom = Me.txtFromNumber
   lngTo = Me.txtToNumber

   For lngCounter = lngFrom To lngTo
       With rst
           .AddNew
           ![Client_Code] = Me.txtClientCode
           ![Invoice_No- = lngCounter '<- May need to think about data type
here
           'If you need to populate other fields and have the data, they
could go here
           .Update
       End With
   Next LngCounter

   rst.Close
   Set rst = Notihing
   Se dbf = Nothing
