Lyra - Change Projectile Speed

Hi Guys, I would like to change the projectile speed in Lyra, especially for the b_rifle class so the bullets behave like a paintball (lowering the speed of the projectile.)
Unfortunately, I couldn’t find an easy way to adjust projectile speed for the rifle class. Does anyone have any advice as to whether this option already exists for the b_rifle class and where to find it?
In the B_NetShooter Blueprint I found the ProjectileMovement Component. With this component the projectile speed can be adjusted. Can I use this component for the B_Rifle Blueprint and if so, how? I would be very happy about your help, thank you very much
