There is a group of techie people that do mess with the program. They have their own group https://proconnect.intuit.com/community/lacerte-sdk-group/gp-p/501
The best the rest of us can do is to ask Lacerte to add this (Help > Lacerte Feedback), and set back and wait a decade of something to happen. I have been using Lacerte for 40 years. I remember when we had to use the multipage spread sheet that showed where every line of K-1 went. A user in Sebastopol CA did a cut and paste of the various input sheets to do each of the K-1's. Ultimately Lacerte incorporated that into the program.
