Rolling momentum!?

How do you keep the character moving during a roll animation? I read root motion is not good for multiplayer so I am avoiding this. I can’t disable input because that stops the player. My animation looks lovely when im holding down the movement keys. but otherwise the character rolls in place. I want to be able to keep the momentum going (i use 8 direction animation blendspace) and disable input (the latter is easy) during a roll. This has to be answered somewhere but I can not find it. Thanks!
