I have finished BG1 main quest and started the Siege of Dragonspear. But I now realized I did not do the side quests that were added in BG1 EE (Ulgoth's Beard and Durlag's Tower).

Is there anything I can do to go back in BG1 EE and do these quests without loosing all the work and time spent in the Siege of Dragonspear?
