Slider with multiple intervals

Currently, the WPF slider has some properties that allow defining and viewing a single interval on a slider: SelectionStart, SelectionEnd and IsSelectionRangeEnabled.

By setting these values

<Slider Minimum="0" Maximum="300" Value="150" IsSelectionRangeEnabled="True" SelectionStart="50" SelectionEnd="200"/>

you get the selected interval in the slider, colored in blue, like this:

What I would like to do is to be able to define multiple intervals - e.g. (50-100), (110-130), (170-200) and (210-240), which would look like this:

Any ideas on how to aproach this issue or what template I should try modifying in order to get this feature?

This may not be an answer but a workaround. I place the slider bar on canvas, then draw to canvas: Highlight segments on slider bar
