[Feature request] Specify output level.
As far as I know this is not possible currently. I basically want to change a level using a SPWN script. Currently, it will overwrite the input level after the script ran over the level. Now, if I want to change the script, the input level (which is also the output level) has already changed and the script can therefore not work properly. I know there is group 1001 (every generated object by SPWN will have it, and get deleted on re-run), but let's say I want to transform a level into a designed version of it self, what would I do with the original level objects? I would need to make them invisible. It would be much more convenient to be able to specify a level where it should be output to.
spwn doesn't modify objects that are already present the level, spwn can only add new objects.
You can perfectly restore the level by building an empty script
