Similar command "ibsad" in VISA

I have a PCI-GPIB card and want to use VISA instead of IEEE488.2 to play with an old telescope.

In my case, the secondary address must be configured frequently.

Could not find  command in VISA similar to ibsad.

Only know in viOpen, I can apply the secondary address (see below value "101" )

viOpen(defaultRM,"GPIB0::18::101::INSTR",VI_NULL,VI_NULL,&vi);

 But if want to other address, I must close and reopen again.

I do not think this is a good idea.

Thanks for any tips!!
