Recording at 96/192 bit rate, preserve when import to 48k

This may sound odd.
I'm much into sound design and use real field recordings sometimes to build my sounds.
I used to have Cubase as my main Daw, there I have an option when importing 96kHz into an 48kHz project, either to convert the audio to to the project rate or not.
When choosing not to convert, the sample is about twice as long in time, it's lowered in pitch, so the sound frequenzy above human hearing is no hearable.
When stretching normal audio in ableton, at 48khz, you get lot of artefacts, while stretching with the above method gives a much more pristine sound with more the overtones preserved.

So I'm wondering if there's a way to do this in ableton directly, may be some obscure setting in options.txt, like preserve sample rate, don't convert audio at import, play imported samples at their original rate?
I realize thoung that this could mess up a thing or two in older projects, where the samples are converted to match the project.
Though, I can workaround this for now by export the stretch sample from Cubase at 48/44.1 kHz but every time you convert, someting gets lost I guess.
Cheers!

When importing your 96khz file in a 48khz project, turn off warp and set the pitch to -12 semitones on the sample. This will make it twice as long and an octave lower.

Thanks, I'll try that, but isn't the file already twice as long, as it plays back at half speed, and thereby an octave lower?
But I'll checks asap!

Seemed to work great! Thanx!

Here's a test, me "roaring" ;)
