I recently had to change the compression algorithm used for our zip archives to lzma.  
Unfortunately FinalBuilder’s 7z actions don’t have an option to pick the algorithm so I had to call 7z from the command line.

It would be convenient to have this setting available in the action directly.

On the Archive Options tab, there is an Archive Type option, is that what you are looking for?

Not quite.  
Changing the archive type will also change the default algorithm used. But what I need is to keep the archive type the same (due to technical limitations we have to use zip instead of 7z) and change only the algorithm.

In the 7zip GUI it would be this option:

The corresponding commandline would be something like `7z a -tzip -mm=lzma ...`

That’s exactly what I was looking for.  
Thank you.
