In Revit 2023 it became possible to filter schedules per sheet, which enables the possibility to have an automatically created Legend on sheets. 

In the BFT template, there are two schedules that can be used. One per sheet and one entire project. All BFT components have been updated with a type image of the symbol, so if the line style/color i.e. fire compartmentation for walls is changed, the image is updated. Open the family and edit the image.

There is a sheet that shows all components in the model.

And there is a schedule which shows everything per sheet. It's possible to place and copy/paste on several sheets.
