Is there a global way to manage subscribers in iPhoto shared albums?

One of the people I share albums with changed their AppleID & now I have to go through the painful process

of changing a subscriber on around 50 shared albums. Tedious to say the least!

Is there a global way of changing/adding/removing a subscriber to iPhoto shared albums?

Wouldn't it be nice if,

iCloud Albums could be placed in Alphabetical order (being able to order by data/name/etc.

as you can normally with folder items).

There was a utility that allowed global changes to subscribers/permissions on shared albums

so you didn't have to dig down into each album to make such a change.

ie. all the things Apple usually do well filtered down to Photos albums.
