Quantization of the loop function

Currently, to use the loop function, the "Select Part Of Track" function is used to select the location to be looped.

However, this function is inconvenient because it can only select one Bar at a time.

I would like to be able to set the quantize to 1/8 bar when selecting a part of a track, or to be able to select without quantize!

By adding this feature, it will be possible to mix with Roll like CDJ and spice up the music easily.
