Dual Fly Combos?

I was updating a new computer and was in the process of deleting old
email when I ran into an ad for dual fly combos.

Anyway, I do something similar with a steelhead rig box thingee. Do
any of you pre-tie two flies or droppers and if so, have you found a
good way to store them for the stream?
