[feature] filter for filename

[shevernitskiy]

There is a add_filter method for specify target file extnsions.
Is this possible to add filter for filename?

Let me descirbe my case to clarify the reason.
I have the file dialog whitch should pick windows or linux executable file. The names are known - app.exe for win and app ro linux (without extension).
So I want to narrow files to pick by array &["app.exe", "app"] like I can do for extensions.
Is this possible to implement?
