Display paperclip after adding media object

I added the automatic media object functionality to a custom program at the row level. When performing a find function on the grid, the paperclip shows as expected on each row that has an associated media object. How do you get the paperclip to show immediately following the creation of a media object for a row? I know I can click the find attachment button, but I want the paperclip to automatically appear once an object is created.

I can add Set Grid Text Indicator function, but to what event would that code be added? I don't see an event specific to adding an attachment.
