Sheet Collection is now available as a category for both Parameters and Schedules.
You can see the new parameters added to the Sheet Collection category on every Sheet Collection node. The parameter values are synchronized to every Sheet included in that collection.
Parameter values show as read-only on every Sheet in the collection since they are driven by the Sheet Collection. If you modify the parameter value on the Sheet Collection, this updates the value for all Sheets (and Title Block Labels if included there).
If you move the Sheets into another Sheet Collection, the parameter value is automatically updated based on what is defined in that Sheet Collection.
