Dynamic sliding/dash in Battlefield 5 [ Edited ]

[Sebash92]

Hello.
Can we set the single push button/ hotkey, for example if someone have it - the side button of the mouse that it would immediately run the sliding?
Of course, only when we run.
I write about it because I have set it in the settings on my side button of the mouse but often as I press twice the crouch button (unfortunately the only way to run the dash) it does not start and just my hero crouch down and up instead of sliding.
I like how dynamic this game is with the sliding option (dash) but Is there a chance for some fix to make it work much better?

up, because I meant the sliding not sliping
