Grade Inputs

On the old Better Canvas, you were able to manually input grades for classes that don’t update grades to maintain the correct GPA percentage. Is there a way to still do this? For example, I have many classes that don’t update things throughout the semester, but still count towards my GPA in the long run. Previously, I have been manually inputting these grades as 100% or 90% based on what my professor has told me, but isn’t updating. Is there a way to input these percentages and save them? T
