You should plan ahead (before or while drinking...) and write down what you're using and get it ready before you need it.
For instance, while the water is heating up or I'm mashing, I will recalculate the hop AA% needed for the recipe. Here's what I do:
I take a baby food jar and place it on the digital scale then tare weight it to 0. Then I add in the hops to the recalculated weight and place a 1/2" X 2" strip of paper in it with #1 on it. Then I take a second jar and measure out the hop second addition and place a strip with the #2 on it, etc.
Once the boil starts I remove the strip of paper and pour in the hops in the wort at the designated times. Once completed I pin the strips of paper back up on the cork board to reuse later. Same could be done for plastic strips with numbers on them.
All too simple if you plan right.
