DialogListItem has an
icon property, and according to the docs
For a list view control, returns or sets the icon associated with this item. You can specify the path of a file or folder to use its icon, or a file extension (e.g. ".txt") to use a generic filetype icon. You can also set it to "dir", "file", "ftp" and "ftps" to use generic icons. You can also extract an icon from a DLL or EXE by providing the path of the file followed by a comma and then the icon index within the file.
it is not possible to specify for example the
collection internal icon in an easy way, so I'd have to extract it from the dopus.exe using the comma syntax as described in the docs which seems kinda hacky for simply wanting to use an internal icons in the GUI script? (even though it's an one-liner)
