How to specify Contains in UI Automation PropertyCondition

Question

I am using UI Automation for GUI testing.

My window title contains the application name appended by a filename.

So, I want to specify Contains in my Name PropertyCondition.

I checked the overload but it is related to Ignoring the Case of the Name value.

Can anyone let me know how to specify Contains in my Name PropertyCondition?

I've tried solution of Max Young but could not wait for its completion. Probably my visual tree was too large, not sure. I've decided that it's my app and I should use knowledge of concrete element type I am searching for, in my case it was WPF TextBlock so I've made this:

public AutomationElement FindElementBySubstring(AutomationElement element, ControlType controlType, string searchTerm)
{
    AutomationElementCollection textDescendants = element.FindAll(
        TreeScope.Descendants,
        new PropertyCondition(AutomationElement.ControlTypeProperty, controlType));

    foreach (AutomationElement el in textDescendants)
    {
        if (el.Current.Name.Contains(searchTerm))
            return el;
    }

    return null;
}

sample usage:

AutomationElement textElement = FindElementBySubstring(parentElement, ControlType.Text, "whatever");

and it worked fast.
