Image Overlay for Video/Image

Has there been any discussions from the Epic team to implement an image overlay feature for video sequences?
I do a lot of post processing VFX integrations and this is very helpful. Lumion has this simple feature.
For example, I would have a video scene from shutterstock I want to include in my TM environment (say a couple walking for example). I would usually take the first keyframe from Shutterstock, overlay it to my first keyframe on TM and match it, then do the same for the last keyframe of both. Assuming a linear path between the 2 keyframes, it works just fine to integrate the two in a post processing software.
If no plans to integrate this kind of feature, Is there any workaround currently?

Thanks!
