Lennox G20R furnace, 2 speed fan possible?

[Fisherguy]

Hey All,
First post here, looks like a good spot for answers to my do it myself home projects!

I have a 3000 sq foot house with the bedrooms, games room etc upstairs. In the winter it gets a little cool up there, I'm thinking a 2 speed fan in the furnace might help distribute the warm air.
Anyone know if there's that option for my furnace? (Lennox G20R03/4E-100-6)

I looked through the manual but didn't see anything mentioned about a 2 speed fan.
Thanks in advance.

not sure if a two speed fan would help you but possibly a helper fan installed in THAT duct that feeds your room might. its a fan in a small 6 inch duct section or a small squirrel cage fan that installs in a flat trunk line. its wired to come on along with your normal fan forced fan. available from grainger supply.
