If you talk about using existing ISO and rebuild them, the answer is no, 
at least not directly. You need to do things in manual way, and you need 
to understand how archiso works to unpack and re-create it.

What profile are you using?

are you talk about "source" root-image or "target" root-image 
(work/$arch/root-image)?

When you want to repeat some step (functions in build.sh(, must remove 
the corresponding "lock" file inside "work/$arch/build.FUNCNAME".

All customizations should go to build.sh:make_customize_root_image().

I recommend to see how build.sh works from both profiles (baseline and 
releng). In baseline, this is the most simple way to build a new 
"archiso", second shows how official releng are build, customizing 
"root-image" and doing other things like splitting root-image.sfs, etc...
