Is there a way to turn off the "reduce to single existing albums" setting on the synchronize tab so the plugin runs against ALL albums? I clicked in that control once to limit it to a specific album and now I can't get it to "clear" the selection and am always forced to pick an album (with "Search in sub-albums" checked).

Hopefully I am just missing something obvious here ...
