Hi. I am so sorry for it taking so long for me to get around to adding this. Work was so hectic and I was struggling to get around to adding new animations. I am not sure if you are still interested, however, I have added the push, pull and grab animations now along with a few other new animations and just wanted to let you know in case. You can find info on the new animations here:

I hope this is helpful and that you are doing well :)
