Adding extra hops

[JayBee]

I`ve got a Brupaks kit ready to go next week and I`m going to add the hop bag by boiling for 20 minutes. I want to add another hop, more for aroma than anything. I intend to boil the first bag in water and rinsings from the cans and was thinking of adding the extra hops to the same pan for the last 10 minutes or so.
Does this sound OK or should I get a second pan on the go for the second hop addition?
Thanks for any input.

Thanks for that Chris. I assume, and hope, that even though the hops are in the same pan, by boiling them for different times they retain their own unique flavours/aromas.
