Espresso,
I don't know of a way to add custom autoformat schemes, but if it's color,
you could change the colors in the palette in that workbook. Tools -
Options - Color. Click the color in the pallete, Click Modify and change
the color. Now anything that uses that particular color place in the
palette will have the new color. You can do this after the autoformat
formatting has been applied (it's now no different than if you'd manually
formatted the cells). This won't affect other workbooks -- each has its own
palette. You can import this palette into other workbooks too.
