SIN COS Encoder on FBL Series, can SPOL < 1?

In the documentation, SPOL is the number is sensor revolutions for a single mechanical (motor) revolution. I would like to gear my SIN/COS sensor so that it can be used to provide absolute motor position for 4 revolutions of the motor. This means that the SIN/COS senor would rotate 1/4 of a turn for every motor turn. This would require an SPOL setting of 0.25, which is currently not possible.

Is there a way to enter an SPOL that is less than unity?

Thank you.
