Release Techs

Ok, so I was wondering, for races like Mod Souls and such that have like six initial release techs, but can only learn like 4 upon creation. Is it possible to just make the techs and just buy them right away after or is there some other catch? I doubt it would be to wait until you hit AA release mastery seeing as more often than not, it locks you out of editing those very techs anymore and only leaves you to focus on the final phase of your release.
