One Gstin And Two Trade Name

Sir in case of the above solution ,will be legally ok if you use trade name separately at different places ?

for eg 

as you suggested 

1st Trade Name : XYZ enterprise

2nd Trade name : ABC enterprise

register trade name in GST as : ""XYZ Enterprise (ABC Enterprise)""

Now can we use 

Hoarding at location 1 : XYZ Enterprise

hoarding at location 2 : ABC Enterprise

or we have to then use name together like ""XYZ Enterprise (ABC Enterprise)"" shown in registration certificate ?
