You can do this, as experiment will show.
Given
global dem "age sex"
global dem1 "age"
you can set
global reg1 "reg hours $dem"
in which case -reg1- will contain
"reg hours age sex"
or you can set
global reg1 "reg hours $dem1"
in which case -reg1- will contain
"reg hours age"
Trailing spaces can also be added as desired.
Whichever definition is last in a session will
overwrite any previous ones.
