find_system(), 'blocktype','inport' to find the Inport and Outport blocks.
get_param() to get the Inport and Outport block names
add_block() to add Goto and From blocks
add_line() to connect

ok,but position may be also need consider,they need keep same horizon

Yes. The position can be specified when add_block(). Or you can use set_param() separately.

The port position of the subsystem block that contains the Inport and Outport blocks can be used to determine the positions of the Goto and From blocks.
