So I am level 26 and doing the grand companies quests. I have finished all but the dungeon one, and decided to join the Flames, but can't join officially yet until I finish the dungeon quest.

The question I have, is since I won't be joining Limsa Lominsa or Gridania's grand companies, would it be alright to spend all the recruit seals I have earned for those 2 before joining Ul'dah? Or do they get transferred to Ul'dah once I join the Flames, and sp3ending them would prevent me from immediately getting my Chocobo if I do that?
