Sorry for misunderstanding! I see what you mean and I've written up this issue. Sorry about that!

In the mean time, I know it's not ideal, but your proposal for a workaround is probably the best solution. You might instead add "(last)" or the equivalent to the last item in the group so that you know that it's the end of that group and can then reveal it in Planning mode and complete the group. Again, very sorry for the trouble.
