Single dataset, multiple layouts, same report

[AndyInNC]

I have a stored procedure that returns the Store, Product Category, Units Sold, & Sales Dollars, but each is reported in different charts.

Almost everything is reported separately. Each ProductCategory gets its own chart for both for both Units and Amounts. So Hats, Gloves, Shoes for Units Sold makes 3 charts; Hats, Gloves, Shoes for Sales Dollars are another 3 charts.

The charts for Units Sold are in a tablix that should be one Product Category per page. (There is a page break between Categories.)

Up to this point, everything works very well.

Then the charts for Sales Dollars need to be displayed 4 per page (2 columns of 2 rows) and there are up to 8 categories, but it could be fewer. (I have the 4-per page charts are in a separate tablix from the 1-per page with a column group for Product Category.)

Two things I can't figure out:
1) This needs to be printable (landscape). How do I manage page-breaks? Should this be sub-reports?
2) Should all this be in the same tablix?

I still have costs to add in here (which may be a separate data set -- I'm not sure).
