Frame rate changing issues

This is probably a very simple question but it's been bugging me for a while – is there a way to change frame rate, by changing the duration?

So for example, lets say I've rendered out a video as 30fps. I then import it back into AE. But I want it to play at 25. Normally I'd interpret the footage and change the frame rate that way, but this keeps the duration the same and then drops frames. Is there an alternative where the the video will play at 25fps, but the same frames will be displayed, meaning it will run slightly longer? Kind of like how when you create an image sequence you can import it at any frame rate.

Thanks!
