Leading in Cmd-T?

Would it be possible in future iterations for the text menu invoked by Cmd-T to include leading?

I can never find where leading can be changed, and always have to fish around it when, for instance, I’ve copied a web address and a bit of text into my notes for a research document, and need to have them clearly associated. That cmd-T dialogue seems to need leading as one of its options.

I’m afraid the Cmd-T font panel is just the standard OS X font panel, and there is no way for me to modify it as it’s one of Apple’s “black boxes”.
All the best,

Alas.
