Record keyframes of Triggers (From Replays Manager) manually without the need of activating Record (Ctrl + R)
I do not know if this exists already, but I think it would be helpful to point your playhead at specific frame of your timeline then hit your Trigger key to manually add the keyframes you set for that said Trigger key in the timeline (without pressing Record). Not sure if it makes sense.
If you select the replay (in the Replays section), move the playhead where you want it in the Timeline panel, then choose Edit > Paste, it'll paste the replay's contents starting at the playhead. However, currently, keyframes in the replay are pasted as equivalent take bars.
