at least 2 puzzles

I try to find more 20 clue sudokus with this layout and no singles for the first step but its hard(time consuming) and the range of ratings seems to be very limited.

I hope that the game is not over and they keep answering problems I encounter by trying to generate nice paterns like this one with 20 clues:
I 'm wondering if it's possible to avoid singles at the first move, but after a night running my generator I still can't answering it.
Better equipped generators like those from m_b_metcalf and JPF may answering this question.
