No it is not possible without a major overhaul of the way that plugin
works. It also requires extensive work in other plugins.

Put animations framework to the top of my work items and then we can

This will need heavy lifting too - currenly we are waiting for the

see any other way to do this other than to completely rewrite these
plugins.
