Data from Access to Excel

I hope someone can help me.

I am developing an automatic relationship between our Access database and a permanent data tracking Excel spreadsheet. One very big component of our data tracking is a daily morning inventory of specific case types. The problem I am having is when the spreadsheet is refreshed each morning, the data and total count of a specific case type is simply replaced. I need some help figuring out how to retain all data specific to the date of the morning's run. I have included an outline format to hopefully clear up the issue:

1. Open spreadsheet and refresh. The complete inventory list appears automatically on Tab 1.
2. On Tab 2 (the issue), I want to have a simple master data sheet that lists the case type as column and the morning's date as rows. I have used 'COUNTA' expression to get a count of the data but cannot figure out how to automatically 'tell' Excel that the next morning's data must be displayed in the row underneath.

Thank you in advance for any help!
