uvm register implimentation for same register with different instances

Hello , 

  I have a scenario as below , 

In the dut , there is a set of registers which acts as control register for different instances of same IP inside dut. There is a control register which controls the set of registers to decide which instance of IP it needs to wr/rd .

I am thinking of creating a reg block for the set of registers and instantiate as per the IP instance number. But I am not sure how the reg wr/rd of each block as per the control register IP selection . Please comment on this problem . 

Thanks
