PCF8523TS Separate INT1 and INT2 on Timer B

Working with the PCF8523TS, and trying to find a way to have Timer B timer interrupt only trigger the INT2.  As is now,  timer A, triggers INT1 only.  Timer B seems to trigger both INT1 and INT2.

Is there even a possibility to have Timer B only trigger INT2.

Any help is appreciated.

This may also explain why there is very little usage of timer B, as discussed here: PCF8523, have source code? 

The combined behaviour could have been achieved external to the chip, but with it being internal it reduces the functionality.

Having them separate would have also solved: https://community.nxp.com/message/979127
