In his 
Q&A Teach-In video Lee Earle shows a method in which the paper used is divided into thirds.  You let spec #1 fill out the bottom "slip" and tear it off (it's perforated for ease of removal), #2 gets the middle section and of course #3 the top... you know who is who by the position of the information... this was used with his Ultra Thin board if I recall but can be used with most any imp system that is of reasonable size (I wouldn't use a 
Butterfly, for example)
You can likewise employ the same device in working with a group of three but not rely solely on the imp pad's stock gaff and with some very limited modifications get miles of extra advantage.
a.) Primary imp gimmick is set into the cardboard front or back cover.  This allows you to remove a sheet of paper or else open the pad with a single sheet laying atop the gimmick -- simple, standard operation...
b.) Roughly 3 sheets down from the "top" (the same point where you opened the pad for the above work) you have a sheet of matching NCR paper (you can find this carbonless paper in a variety of colors and even with lines that match yellow/legal pads, etc.) with this you can either divide the new page in half so as to get two transfers of information from two more specs or just use it for stealing a single (large) image.
c.) The inside front cover (in this case) has a very smooth glossy blank white surface... it's not overtly obvious so it's nothing to worry about. As if a second thought, you re-open the pad but from the front side vs. the back (as before)... rather than spoil things here I'll just suggest you look into a method known as a "Fields Device"  
 
 
Learn to sit down with an item and list everything you believe you can apply to it for using it in a solid bit of business or, as I do, to help obfuscate methods.  For example, I might use a pad that's been set similarly to the above just to throw those "in the know" off my trial because of the casual and different modes of having folks jot down information... not always part of the same routine (you don't have to use separate gimmicks for each act after all). 
With a simple shirt pocket styled notepad you should be able to readily deliver a stock billet routine (other than any kind of Center Tear... I mean BILLETS), a Psychometry styled act (ala Ronaldo the Great), and a Drawing Dupe... and that's just the easy stuff that can be done.
