There is no way to add more than 4 weeks, since it would demand modifications of the whole VBA code, set and reps schemes and so forth. The solution is to print for first 3 weeks, and then print for next 3. Printing more than 4 is so small on A4 paper, so it wouldn’t be visible either.
There are no 3 nor 5 days template in the latest version due VBA code involved in saving programs. I suggest to print 4 day template and leave one day empty. Not perfect, but also more visible than 3 days on one paper.
