help creating layers

i'm curretly creating a template. the company standards goes as
follows:
x- for existing works
c- civil proposed works
s- structural proposed works
e- electrical proposed works

i have alrready creted about 50 layers with the x prefix (existing
works), i have now to create the layers for the rest of the other
disciplines wich mostly of them contain the same sufix i.e.
x-pav (existing pavement)
c-pav (proposed pavement)

now, since i already created mostly of this layers is there a way that
i can copy and paste all this and just change my discipline letter?

do i have to type all of this layers againg just to change on letter?


any help would be appreciated,

thanks in advanced
