I believe that text should be on a Phase and Not View Specific.
Consider that you have designed the ultimate plan set with all of the bells and whistles. Now you desire to scale the project back to cut costs or for any other reasons. If you have a 100 or more views of the ultimate design this means that you now have to duplicate these views and the sheets they are on to obtain the scaled back design. Then you need to delete the text that no longer applies and hope that you get it all right. What do you do if you made a mistake or what it another way? The amount of effort required is inconceivable!
Then if you want an in-between design you will again have to duplicate all of the views and sheets again. This seems to be a very unreasonable way to achieve simple variations in the design.
Wouldn’t it be more efficient to just change the text that labels an item to the same phase of the item? It is true that you will need to change the Phase of the 100 views to the achieve the result. However, the Sheets these views are on could remain as they are and you wouldn’t end up with hundreds of duplicates.
