Yes.

Your three states A, B and C are islands, right?

Let's assume island A starts on row 002, B on row 005 and C on row 008

On one track at the end of island A, B and C you enter (in the FX columns)

FX1 FX2

PRF2 032 STSP 002

PRF2 021 STSP 005

PRF2 019 STSP 008

That will result in 25% chance of a jump to island A, B and C each and there is a 25% chance of no jump at all thus repeating the current pattern.

In other words:

The active pattern is repeated with 50% chance and each of the other patterns have a 25% chance of being executed. Adjusting the numbers after PRF2 changes these.

This is a simple example of a Markov chain for islands

If you need more explanation as to why the above yields the described effect, feel free to ask.
