I use the system laid out in the CCA Umpire Improvement Manual, with some modifications for HS. For example, once a sub comes into the game, I can circle her number because she will no longer be available as a sub in the collegiate game. But, in the HS game, a circle around a sub says to me that she still has one re-entry. When she re-enters the game the second time, I put an X over the number that is already circled. I believe, if I recall correctly, this is pretty much the same as Emily's system on cactusumpires.com. (Been a while since I looked on there.) No special card is needed. I am really not sure what it is that you are finding cumbersome about this form of lineup card management. I find it very easy to do, and very easy to track. I can tell when either the DP or FLEX are active, and when they are not.
