You can still "name" your label. However you need to have a unique identifier, maybe in the tag so you can identify it.
Lets say you want to create a new label with a permanent handle so you dont lose it.
Dim a Label in 'Globals':
and in activity create initialise it and add it to the scrollview.
So you should be able to change its value if you need to.
If you have more labels then create an array or list of labels.
If you need to find a particular view from a parent (like scrollview's panel) make sure you put something in the tag to identify it.
