When setting up the following SFM program, SFM was able to put Certus blocks in the output slot of a circuit Slicer.

SFM code that had been run -

NAME "SLICERS"

EVERY 20 TICKS DO
    INPUT FROM BUFFER
    OUTPUT TO SLICER
    FORGET
    INPUT EXCEPT *block* FROM SLICER
    OUTPUT TO INTERFACE
END

Specifying the side of the slicer (NORTH SIDE for instance) was able to work around this.
