Sequencer: Alter animated camera to aim in different direction?

Hi guys,

I animated a cinematic camera within my level sequencer. Unfortunately I have to change the “aiming direction” of my camera and therefor the translation and rotation of all keyframes.
I’m new to animating cameras within UE4. In Maya it’s possible to select all keyframes within the dopesheet or graph editor to adjust the scale/translation/rotation accordingly whilst preserving the existing animation.
Can you guys help me out so I don’t have to redo my animation?

Thanks a lot in advance
