[srihari_230]

hello,
      i have created a circuit diagram in eeschema software,but i need more 
circuit to be added and i want to create new sheet,but i didnot found any 
option.so i clicked on new schematic project and created another circuit.when 
clicked on annotation ,the annotations again started from number 1.
              how can i link two schematic sheets for correct annotations.
