Where does it say that, because it is wrong and needs changing. Plugboards templates aren't special. There might be some restriction on using GUI-only functions in a plugboard, but I don't think so.
One possibility that extends on @ownedbycats idea is to use a combination of a stored template and a custom text column. The stored template first checks if the column contains a value, returning it if so. If the column doesn't contain a value then the template computes the "default" result however you wish.
Using a stored template makes it easier to test and maintain. Using a column as an override means you change only the books for which the template produces an undesired result. Removing the value from the column for a book automatically reverts back to the algorithm.
EDIT: Rereading I see you anticipated my idea. Sorry about the noise.
