Change the leading of a character style???

[Char t]

Hello, i have a doc with a mixture of paragraph and character styles in a single paragraph inside a text box. My problem is when I set the leading of the paragraph style to what it needs to be, the tops of my headlines are cut off (the font is larger than the paragraph leading allows). Is there a way to set the leading for a character style that will override the leading of the paragraph??? Thanks in advance!
