First of all, you can open the datasheet of a component from its configuration dialog.
And in the data base, basic specification of that component is described.
I checked both SCB-SPI and Non-SCB-SPI
SCB-SPI: databit can be 4 to 16-bit
Non-SCB-SPI (SPIM): databit can be 3 to 16-bit
So I'm afraid that the standard SPI components do not support 100 bit transmission.
But you can set databit to 10 bit (your word) and with 10 transmissions,
you can send 100 bits.
