[FEATURE REQUEST] Make adding many parameters to Sequencer easier

Adding a complex actor to sequencer can frequently require adding a number of parameters. These have to be added one by one. In many cases they are a few levels deep (static mesh component-> Material element → parameters → specific parameter). Complex objects such as {Post Process Volume or third party apps such as Ultra Sky) may have dozens or even hundreds of parameters that need to to keyed if only to prevent them from changing due to other level sequencers makign 'gloab; changes.

Consider dealing with this similar to how Take Recorder deals with Metahumans. A whole list of the hierarchical parameters is displayed making it easy to enable/disable full sections or multiple individual parameters with a simple click. That would make adding parameters easier in Sequencer.
