Option to create ZIP from an existing engine build

[Arshia001]

An option to create a ZIP from an existing build will be very helpful, specially when trying to figure out what to include in the ZIP. I did try to create it myself, but the end result isn't exactly up to par.

This option is already available. If LocalBuilds already exists, UBB will prompt you to zip it instead of building.
