Add an icon in CCv5 listing and link to an action

Hello,

I have a listing in which I would like to add an icon for each line. The action on this icon will open a modal window.
My question is how to add this icon in the listing.
I mean, the only think I can do with this is to add in the "FrontList/Settings/ColumnsList" a title to create a column for this icon, knowing that this icon does not have any corresponding of my model.field.
In the "FrontList/Settings/HTML and Images", I do not have any corresponding Model.field.

How can I do that?

Thanks in advance

Hello,
I continue to investigate:

In the column list, I wrote

_UPLOAD_: Upload Files

In the HTML field box:

 _UPLOAD_:<img title="UploadFiles" src="http://.....img.png">

In "FrontList/Actions", I added a new action: upload, and in form event: FileUpload:load

How could I link _UPLOAD_ with "upload" defined in "FrontList/Actions"?

Thanks in advance
Bertrand
