Import empty group addressess from ETS

[Tokatubs]

Have a project that will be imported into the Lm5. The file has been created in ETS5 with group addresses. But lot of them are still empty because products have not been added yet. 
But i want to import them into LM and when the programmer links the products i the telegrams start. 

Reason is that i am doing an integration to bacnet. And therefor i want to start on this work, and the work with the BMS system on the other side.
