How can I annotate the wire designators in a sequence? 

I have found that my wires and core designators are randomly assigned as W2,W3,W5,W7,W8,W10. I wanted to have a sequence W1.W2, W3.W4, W5, W6.

Does there is any auto function(addons) that can do it? Also, I want the correct the sequence of core numbers.

Additionally, Does there is an option to start numbering from a specific number?
