Various Font Styles for Immediate Tempo Text

Is it possible to have different Font Styles for Immediate Tempo Text, for example if I want Adagio 12.0pt Bold and a tempo 10.0pt Italic?

No, not at the moment, because the same font style is used for all non-gradual tempo changes, i.e. both immediate and relative tempo changes use the same font style. We know that there are further conventions for the appearance of tempo changes, particularly the use of italic directions shown on every staff rather than bold directions shown only on one or two staves, and we hope to be able to accommodate those in the future.
