Base member syntex in input template

Dear BPC Friends,

I have to pull the BASE member of  around 30  PARENT member using EPMDIMENSIONOVERRIDE function. I know the syntax for this is BAS(111),BAS(222),BAS(333),BAS(444).........etc. 

So my question is, can I use syntax BAS(111,222,333,444).... etc. or is there any other syntax to pull the base member of 30 parent member using EPMDIMENSIONOVERRIDE function.

Kindly advice,

Thanks,

Rahul
