Delete layer references in Draftsight

Hi Everyone,

I am trying to delete a layer and it deletes all child layers under it obviously (they were saved as dwg using altium). But I still want to keep the information on children layers. Are there any ways to break the link between layers or move them up the tree? such that they are not affected when I delete unwanted ones?

Any help is greatly appreciated!

Thanks,
