This is a possible solution via a work around and may not be practical in a production environment but here goes:
I've looked for a vb solution to the issue but there seems to be no way to return the current active Bookmark so as a result we're left with the below:
Bin the Bookmark object. Instead use buttons to select your bookmarks (if there are hundreds obviously this won't work too well), lets say for simplicity we have BM A and BM B, you'd have 2 buttons (you guessed it one labelled 'A' and the other 'B') upon clicking the button labelled 'A' an action is called to 'Apply Bookmark' A and then (here's the crucial bit) set the value of a variable (vCurrentBookmark?) to 'A'. Conversley when button B is pressed BM B is applied and the vCurrentBookmark is changed to 'B'.
In theory this could work for any number of BM's but above a few it's going to cause issue of managability...as I said; 'Cowboy workaround'.
t depends on how you define an "Active" bookmark. Bookmarks set a state but are no longer in play once the state is set. The same state matching a given bookmark could be arrived at through selections. And a user can modify pieces of a bookmark state after the bookmark is applied, making it no longer "active/matching".
In addition to Matt's suggestion above, Jonathan has offered a novel take on bookmarks here:
