I only know the hit diagonal twice for shoryu, are there any more?
Sakura otoshi is the same motion of course, aside from that, no.

This one helped me tons with my cr.MK~shouken…
On a stick with a square gate, hold an offensive crouch. The stick should be at the diagonal. When you want to execute a dp, just move the stick back until you feel/hear it click, then immediately bring it back to offensive crouch and press a punch button. You won’t even Have to move the stick all the way to the down position, just enough to get the stick to click. It works like a charm. Good luck.
:r::df::r: also works for DP motion, helps getting HP xx Shou I find.
:d::db::qcb: works for her Super/Ultra motion too.
