I have a question about excel.

Is it possible to save the sheets in the workbook seperat?

When I save the Excel dokument i want both the workbook and the sheets to be saved seperat.
So when I open the workbook all sheets are included but when i choose to open a sheet only that sheet is opened.

I got a screendump here to show what I mean.
