New to opentoonz, is there a way to tween already animated "object" ?

I used to animate in adobe animate but I need to change programs for reasons.

I used to make a lot of "symbols" in animate which was converting drawings/animations into a symbols in which you can edit the animation and continue animating it, you could exit the symbol and enter main scene again where the symbol is still here and then for example tween this symbol, making it possible to animate an animated object, for example tween an animated background

Is there a way to do animation within animation, or as I said tween a animated "object/symbol" in opentoonz?

would love any tutorial links or just explanation on how to do it and if it has any name for it so i can search it on youtube or internet, i wasn't able to find anything yet or I might've missed it
