Specify Labels including HTML?

Hello – might it be possible to enable the plugin to allow html code to be accepted in the price label settings?

For example, if the price is blank, and the price label is set to “Price on Request”, it would be great to be able to specify an html anchor wrapped around the “Price on Request” to link to a Contact Us page, or even a simple mailto:, for example.

I tried doing various variations, e.g. wrapping in a <span>, or in an , and such html was rejected when I tried to save the setting.
