Change existing Themes with Theme Community Creator

[Kedog]

Is it possible to import an existing Theme and then modify it? I don't necessarily want to create a new one. I would like to use an existing theme and just change a few details. Is that possible?

It requires the CTC theme's source files. if a theme was not made within CTC, or even if it was and the author hasn't shared them, then no it's not possible.  you cannot import into CTC a theme's published code that Big Box uses, it's formatted different than how CTC does stuff.
