As of now, the only option I know of is to use TBrac manually, provided that you have it. I say manually because TBrac 2006 is not able to import bowler information from any version of BTM, and from only BLS-2013 and older.
It is not known if a newer version of TBrac, as yet not advertised, will be able to import from BTM tournaments to combine contemporaneous events (not divisions) into Brackets. It should function fine for league import as TBrac did in years past.
Always check, download, and install the most recent update of your software to ensure that issues may have been corrected.
