Filtering: How to show values from hidden column

I have two columns in a grid. The first column displays an image based on a value. When specifiying a #select_filter on that grid the combo is filled (as expected) with the values:

<img src='/images/reddot.png'>
<img src='/images/greendot.png'>

What I would like to do is to create a hidden column with the values "Yes" and "No" and have those values populate the combo box on the first column that is displaying the images rather than the actual HTML text as above.

Thanks in advance.
