Does spi-gpio and bitband support 3-wire Bidirectional most/miso share pin usage?

I have a device use 3-wire spi which are CS,SCK,and a DATA for read/write.( maybe a.s.k.a SISO) The command format like as p.18 in www .newhavendisplay .com/app_notes/NV3035C.pdf The spi-gpio can't register miso and mosi for same GPIO pin. Also I traced SPI-3WIRE flag it seems only support half 3-
