Counting # Of Imported Rows For Each Import Process

hi, I am importing data daily to many tables, I want to keep track of the #of rows for each import process. I already have created a trigger as follow:
CREATE TRIGGER tr_bcp_log ON dbo.A
FOR INSERT
AS

declare @name varchar(30),
@row_count int

select @name=name , @row_count= @@rowcount
from inserted

insert into bcp_tracks (name,row_count)
values(@name,@row_count)
GO

The problem is that I am getting a row for each inserted row in table A.for instance if I have 500 rows in table A, I will get 500 rows in the log table like this
table_name,#of rows
A 1
A 1
A 1
etc up to 500 rows for table A

This is not what I want, I want to capture the num of rows for every bcp process , so in the log table I want to see the following :
table_name, #of rows
A 500
B 600
C 450
A 250
etc

Any help ?

thanks

Ali
