It could be possible with an option like
--autosubmit <id>[=list of values to be set]

In your case the list of values can be left away:
--autosubmit fDownload

It would require HTML/FORM parsing, which - i assume - partially exists in 
wget. But then, more and more web pages become javascript generated within the 
client... wget would need a javascript interpreter to work as a robot 
(simulation of a user):

1. load that page
2. simulate a click on item a
3. simulate a click on item b
x. submit form <id> with the following values

Why not report it as a wishlist bug ?
