Subtotal by Date and Summary in Lists?

[fmckinnon]

Hey Gang,

The Short story:
Want to be able to have the same "subtotals" options (ie. at each change in
"DATE" use function "SUM", summary data below, etc) that are available to me
in Data > Subtotals, but within a List Manager. (The Data > Subtotals feature
is greyed out in List Manager)

Details:

I hope someone can help me figure this out. I've got an ongoing list that
requires the use of List Manager. (it's an ongoing list of orders and net
P&L, and I often use the list manager sorting features to display ONLY the
rows from certain vendors, etc).

Without List Manager, I can choose "Subtotal" from the Data menu and have
the option to display the subtotal by date, under each date. This is great,
and exactly what I want.

However, with List Manager, I can only go to the "show totals" line, and
choose the "Sum" function to show a total at the very bottom.

I'm pretty sure it's possible to make the "at each change in DATE, use
function SUM" formula ... but I have no clue how to do it. When I look at the
actual formula, it just looks like a SUM formula of all the cells. I have no
clue where the information is that makes it display as daily subtotals -
there are options like "display totals underneath data, page breaks, etc".

Thanks in advance.
