Multiple calculations based on repeater fields

I see that the “Calculate repeater row value” in the Repeater Field block settings can either default to the rows count or it can be a custom value for each row.

But is it possible to have a form with a repeater field and have both ?

• a calculation field outside the repeater field that sums up an amount to calculate a total amount, and
• a calculation field outside the repeater field that counts the number of rows.
