Surround panner

Since the addition of Firelight into Resolve, there is a problem with panning the sound only to LFE channel.
For example, there is 6 mono Wave ( each for L, R, C, Lfe, Ls, Rs) and you need to send each file to their channels. There is no instrument as it can simply be done - only using crutches: Reassign each mono Wav to 5.1 Wav and specify for each channel. Then on the timeline create 6 tracks 5.1 and put each Wave on some track.
