Ability to specify an attachment display name

[tothewine]

This is about the 'attachment' field type. When I upload a file I would like to set either a description or set the displayed file name. I have many situations where the file name is something like this 'screenshot_2018-12-07_16-42-12' but after putting it in attachment field I want it to be modified in 'example 1' without having to reupload for example in kanban view there is no thumbnail (having it in kanban would be useful too) so the only thing to distinguish one from another is the file name.
