Upsampling fixed to "power of 2" Sampling Frequency

There is an option in my Rivo+ to upsample the bitrate and sample frequency to a ‘fixed’ output.
To prevent rounding errors and phase distortion associated with fractional conversions it’s better to do it natively in “power of 2”.

My DAC can handle max 768kHz PCM but not all conversions are good because of the “power of 2”
Like 44.1kHz should be 705.6kHz @ output instead of 768kHz.

Is it possible (or new feature) to let the system checks the samplerate and output to MAX with respect to the “power of 2” so it outputs 705.6kHz instead of 768kHz for 44.1kHz signals and 48kHz signals will be 768kHz (and on) ?
