New Professions as secondary for old characters?

Anyone know if we'll be able to change our ascended prophecies characters' secondary professions to Ritualist or Assassin? (I wanted a Me/A but i dont like the appearance of the factions Mesmers... for this character.) I know that characters can 'sail' between both campaigns.

I think you can do it by getting your Tyrian character to an outpost on the Canthan mainland called 'Senji's Corner'. There is an NPC there who will let you change between secondary professions for 500g.

See this thread for a guide on how to do it

ah, thanks... i should do a better job searching
