Make an object rotate with triggers

Hey All , Lately I was trying to make a 2d object rotate using a slider back and forth but for my surprise there's not any action of object rotation in stroyline 2 , I tried to do some work around  
1- creating  multiple new states of the object didn't help too as the rotation options are dimmed
2- creating many layers of the object in the same slide with a constant rotation angle difference between  each one , this actually worked a little bit , but i found it so exhausting specially if the range of the slider is more than 4.

Did anyone before come across this issue ? gratefull
I'll be very grateful if there are any new suggestions other than the tried ones.

Thanks
