How to add an Icon to a AddIn button tooltip?

Here is one for the developer gurus...

I'm using ArcMap 10.1 and developingi in visual studio 2010 VB .net. I create a form, drop a button on it, drop a tooltip control on it and under the properties of the tooltip control I can set the properties ToolTipIcon to Info and ToolTipTitle which gives me a nice professional looking tooltip to aid my users.

Now for an ESRI AddIn button I can set the tooltip text in the Config.esriaddinx file as shown below:

<Button id="GDI_btnPointAnalysis" class="btnPointAnalysis" message="Point Analysis Tools." caption="Point Analysis Tools" tip="Point Analysis Tools" category="Tools" image="Icons\AnalysisDS.bmp" onDemand="false"/>

Is there anyway to add an info icon and title just like my button on my form?
