[REQUEST] - .name() Categories and Grouping Animations in Sequencer Effect Manager

[MrVauxs]

Is your feature request related to a problem? Please describe.
There are often times where I am tempted to make an animation .private() due to either not wanting to spam the Effect Manager or otherwise thinking its going to clog up the list with things I don't want to remove by accident while removing something else. Persistent token effects, scene additions, etc.

Describe the solution you'd like
Provide an ability to group Sequences in the Sequencer Effect Manager. This would allow for modules that create animations to have their own dedicated subheader in the Effect Manager, making it much easier to identify where an animation comes from without having to put it in the animations name, which often can become very long.

Describe alternatives you've considered
I do not have any alternatives at the moment.
