Intelligent Copy Into New Instrument During Sample Load

hi. Let’s say I’m loading a 380mb wavefile and it takes a while for it to load. While it’s drawing the waveform, I select a segment of the sample which has loaded, but also a segment of the sample which has not yet loaded. then click on Copy into New Instrument.
the resultant sample is a mixture of both - Renoise tries to copy what’s-already-there, and what-will-be-there-once-the-sample-gets-loaded, but the bit that hasn’t been loaded, is not full (yet the wait for the copy is pretty long - it would appear that renoise tries to wait till the selection you’re copying to a new instrument is fully read, and then still end up copying only small bits of the audio(resulting in mostly silence with some random spikes).
