How to change RootMotionMode via blueprint?

Hi

It seems that there is no possibility to change RootMotionMode during runtime via bp in unreal 4.6. (I can`t find AnimBlueprint setter for this enum and/or standalone node to do it).

I need this functionality to be able to switch from root-motioned animation to ai movement (like “Ai move to” is not working in root motion mode).

Any suggestions?

Thanks
