Adding extra frames in animbrush

Hello Jan@cosmigo I know you are busy but please consider this setting for the animbrush. Animators often animate on what is known as 1s 2s and even sometimes 3s. What I mean is often animations are singular one after the other frame that makes up the animation. But often to make an animation smoother animations have the same frames repeated 2 or even 3 times. My solution is have the amnibrush settings have a setting that allows the user to repeat frames by one or more frames. Maybe it could be a checkbox that says something like “repeating frames before moving to the next” and the user could add as many frames to repeat as they wish. Thank you any help is greatly appriciated.

it would also be nice to have an extra frames option in the “make 3D animation” requester any help is greatly appreciated.
