Change Clip Speed with Duration

In the "Change Clip Speed" dialogue, it would be great if the duration could be entered/changed manually and the speed adjusts to that duration. I ofter have to sync clips with audio and a reference image to another clip, i would be happy if this would be possible in davinci resolve so i dont have to switch to Premiere for this. I know its not something for everibody but maybe someone sees use in this and can back me here

allready sent an request to BM but it does not seem to find its way in the program.

Thanks
