Can you flip a switch in LUA to control which things appear and which things don't appear in the Undo Graph?

Puzzle 2541 gave me multiple ideas for new recipes to code. One would be to analyze a large group of *ir_solution files, quicksaves, and autosaves. I know that some of these files have frozen segments while others have bands. I would like to end with all these solutions in the Undo Graph ordered by score but with all their frozen segments unfrozen and all their bands gone. I think I would need a LUA command that would stop sending things to the Undo Graph until I removed a solution's bands and frozen segments. Then I would need another LUA command to send the resultant solution to the Undo Graph. Then I could use the first LUA command to stop sending things to the Undo Graph until after I download another solution and get it ready. Do such LUA commands already exist? If not, please make them.

It would also help for this recipe to be able to tell evo'd solutions from solo ones. I think when you switch from evo's to solos or back from solos to evo's, the Undo Graph resets itself. This makes me think I'd have to run my recipe twice, once to do all the solos and once to do all the evo's. Is there a LUA command that can tell evo's from solos before it loads them into the Undo Graph? Is there a LUA command that prevents the Undo Graph from resetting when it switches between solos and evo's? If such LUA commands don't already exist, please make them.

Thanks!
