Copy Multiple Networks in ModSoft?

I'm running Modsoft V2.5 program software for a Modicon - Quantum Processor.

Segment Status Display:
Seg Networks
1 1-300
2 1-100
3 1-100

(I've got 300 networks in Segment 1 and 100 networks in each Segment 2 & 3)

I need to put a CHS command/block in Segment 1, Network 1 by itself with no other networks in segment 1.

-- What is the best way to do this?

-- Can I copy multiple networks from one segment to another?
(copy the 300 networks for Seg_1 to Seg_2)

-- Can I copy/paste or rename Segments?
(Rename segment 1 to segment 2 and insert/add a segment for my one rung of logic).

Any help would be greatly appreciated.

Thanks,
Brian
