There was a python script for wallet management on the bitcointalk page that could 'merge' wallets! IDK the name sorry ..

You could also just import your private keys. 

I donated to AGS with both Bitcoin and BitShares-PTS.

My current understanding is that to claim one's LottoShares, one simply replaces the blank, random LTS wallet with whichever wallet the AGS were sent from.

Leading me to the question: is it possible to combine my BTC wallet and my PTS wallet into one all encompassing AGS wallet for import into this and future DACs?
