Importing multiple individual authorities to a local data source -- persistent selection

[atomrab]

The free-text filter for the authority list when selecting authorities to import is a massive improvement over the previous ctrl-F technique I was using. But I have noticed that if I search for a single authority, select it, and then search for another authority and select that, the first one I selected ceases to be selected.

I can get around this by using the filter for the first authority, erasing the filter (which leaves the first authority still selected), and then using ctrl-F on the whole list for any subsequent selections. But it would make more sense if prior selections continued to be selected even when subsequent authority filters were applied.
