Break running header onto two lines after a certain character Power Headers Forum

Is there anyway to break a running header onto two lines automatically when it sees a colon?

For instance, i sometimes have colons in my article titles, something like this:

'How to make cakes better: the ins and outs'

In my running header i would like the para to break after the colon onto a new line as some sentences look bad when just a word or two drop to the next line and it would loook neater to break at the colon. Would it be a case of having a character style applied to any article text after a colon and then setting up two seperate running header lines?
