Partial Reload of concatenated files

I have a table SALES_DATA in which a number of different source files are concatenated. I need to replace the contents of only file SAMPLE4.XLS, How would I go about doing this :

SALES_DATA:

CONCATENATE(SALES_DATA)

LOAD *

FROM SAMPLE1.XLS.......;

CONCATENATE(SALES_DATA)

LOAD *

FROM SAMPLE2.XLS.......;

CONCATENATE(SALES_DATA)

LOAD *

FROM SAMPLE3.XLS.......;

CONCATENATE(SALES_DATA)

LOAD *

FROM SAMPLE4.XLS.......;

STORE SALES_DATA INTO [...............................](qvd);
