make file_column_field editable after file is selected

Hello.

I am using the file_column plugin to upload images. I've noticed that the file_column_field tag produces a text field box with a browse button, and when the text box is clicked on, it automatically browses, instead of just placing the cursor in the text box. Is there a way to change this default behavior?

I ask because there is a scenario where once I've selected a file to upload, I can not clear it out. I have to select a different file, but there is no way just to clear out the file I selected at first, and leave the file_column_field empty (which is a valid case for me). If this text field was editable, instead of automatically browsing, then I could just delete the path from the field.

I've been searching the doc online but can't seem to find a solution. There must be some options I can pass to file_column_field??

<%= file_column_field "profile", "photo" %>

Thanks for any help and insight!!
