Is there a shortcut for DBZ Budokai Tenkaichi 3 for the analog?

[FeudalKnightPlayer]

I'm playing Dragon ball Budokai Tenkaichi 3, and i noticed in the battles that when 2 special attacks, like kamehameha vs galick gun, i need to spin the analog, and i use WASD to spin, but sometimes my fingers are slow and i lose it, and instead pressing on the following order: WDSA, can i use only one button to simulate the keys i'm pressing?

can i use only one button to simulate the keys i'm pressing?

I don't have an idea about this.
But, you can try using mouse as analog/control stick.
