Rather than importing as a hotlink file you can import as an Xref.
I believe when you do this you will have controll of the Xref layers separately.
They will list below all the regular layers of the master file.
P.S. when you place a hotlink file you chhose a master layer to put it in.
You can't change this afterwards except to delete the hotling and place it again.
As Kombibob said if you turn off this master layer then the entire hotlink will be turned off.
If this master thayer is on then you can turn on/off any of the other layers and the main file and hotlink file will respond the same.
With a hotlink file you can't manipulate the layers independently from the master file.
