Setting Proxy for "RSS Feed Reader"

It will be nice that we can set http proxy for “RSS Feed Reader” as we can do for “HTTP Request”.
it is so crucial for servers that has not direct access to the internet, and they the access to the internet via http or sock5 proxy.

yes Exactly.
Is it feasible to implement?

Yes, should probably not be to complicated.
