is it possible to use another output than MCO to generate an arbitrary clock (16.777216MHz) from an internal PLL block?

I want to use a different PLL block than PLL1 to leave PLL1 specific to SYSCLK generation; and for example use PLL2 to generate my arbitrary clock.I see that SAI blocks use for example PLL2 or PLL3 but I don't know if it is possible to make an arbitr...
