ThunderBird 3 - "Archive it" in filters

hello @ all

I'm usign TB3b4 now, I use frequently the filters.
now a filter is set to -move to archive- message older to 60gg but, it 
is not equal to press the "archive" button in the mails, in this way 
infact the mail go in to a subfolder with year automatically. With my 
filter, mails go to archive folder, not in subdir; the button "archive" 
there isn't in this folder, I must drag mails in subfolders manually.

I would an option with "archive message" in the action section of filters

sorry for my english and thankyou @ all developers!
