Can we get 'Sprint breaks out of ADS' option

I'm playing with mouse and keyboard with toggle zoom for infantry. I can't use hold zoom as i feel it changes the pressure on the mouse to the table surface which makes it harder to finely adjust aim while zoomed. This generally works fine for me with one exception.

When I ADS and see someone already taken sight on me or someone gets up onto me too quickly so I want to attempt to evade I need to toggle aim again then toggle sprint or movement to slide in order to evade. This works fine when the visual feedback is fast for weapons that ADS quickly however on weapons that do not the visual feedback is just too slow that we are no longer aiming so I often then 'toggle' aim again to end ADS however as I'm already un-aimed and even if the animation has not completed yet I end up going back to ADS and I'm now stuck in aim mode while trying to sprint...this obviously does not work and invariably I get killed in this situation.

I feel my reaction speed is not the problem here but the game mechanics prevent a smooth execution of my choices. Yeah skill is always a factor and I don't think ADS speed needs to change in any way to avoid this.

What would be great though would be if enabling sprint while ADS could actually break out of ADS directly as this is what my muscle memory wants to do.
