UVM_REG:: How can we use multiple bfm drivers to same regmap using uvm registers

 
We have to use multiple bfm driver to regmap and at same times we don't want to change UVM API's for example:

uvm_write
uvm_read

But I see that in connect stage regmap default sequencer is set to one of them BFM sequencer?

How can we make regmap to use two sequencers and use uvm API's at same time?
