add knx devices

[otravex]

Hi, I have a logic logic to which I want to add new KNX devices. The problem is that I do not have the previous KNX project.
 Can I import Logic Machine a KNX project only with the new KNX devices? 
When importing the new project would lose the previously imported devices?

Thks!!

LM cars only about group addresses and while importing only new are added and old are not touched. No problem for LM here but not having full KNX project is not a great idea.
