Is it possible to use a selection filter based on file extension (ex: "*.dwg") when usin aaApi_SelectDocumentDlg* ?

Using aaApi_DocumentSelectDlg  (or similar dialog) it is possible to define what are the selectable file based on their extension.

Unless I am mistaken, it is not possible to do restrict documents of a specific extension using aaApi_SelectDocumentDlg, am I missing something obvious ?
