Where is the Compile Footnote Formatting Control

[pseingalt]

@AmberV

If I supply an override to the body text with something like 10pt Menlo, and then override all footnote text to 24pt Baskerville (to test in extremes), then I get precisely that.

How can I do that? Except the body text will be 11/13 Sabon and footnotes 9/10 Sabon?
