PCA9541: give bus control?

On PCA9541 I can select which master takes control of bus, every master can take control of I2C bus.
I need slightly different thing: I'm using PCA9541/03 and I need Master1 to take control of I2C bus, write data into I2C device, then give control to Master0.

I can't program/modify Master0 code, that's why I need to give Master0 control of bus accessing PCA9541 only from Master1.
Is this possible?
