INCLUDE-ONLY-FILTER !!!

:idea: Why there isn't any FTP-Program with an INCLUDE-ONLY-FILTER :?:
If there is a huge Server with 10 GB Files and i want to Download ONLY HTML-Files, and i want to Download them immediately now, without creating first a List, there isn't any FTP-Program with this simple Function :!: :!: :!:
I am very disappointed :!:
The regular expressions are not very useful in the exclude filter.
Is it possible to implement this simple function in SmartFTP ?
Greats
