So you mean you're using

, instead of

for Dash?
or want to use

and

(at the same time) for manual(with arrows) spin shots?
I'm trying to figure out what you want to accomplish because I might be able to help you.
I did a lot of xinput modifications with my PES controls using this tool:
https://www.play-old-pc-games.com/compatibility-tools/xinput-plus-tutorial/
Using this tool you, can remap "Dash" to

and remap "close control/finesse shot" to

.
Personally, I use it for manual crossing. When I press "

", the "

" is being pressed too without me pressing "

" physically. So all my crosses/lob are manual. Direction arrows are OFF.
I also use this app to disable

+

(early cross), because it's assisted on PA0.
Play with it. A very nice remapping tool.
The settings I use is also installed on my online opponent's(cousin's) PC, so that everything is equal and we're both manual as possible.
