Yes, you can use the name passed to glp_ios_add_row to find the row with
glp_find_row. Note, however, that glp_ios_add_row adds the row to the
local cut pool, not to the problem object (unlike glp_add_rows), so it
may happen that for some reasons the mip solver does not include that
row in the problem object at the end of the round and just discards it.
