Subclass cert question

[tyrfaxiz]

I have a question about cert.
I wanted to make OL/EE on my sub, i need cert from OL for my main.
I can't take OL as retail subclass but no problem to take it as a DN subclass.
So my question is:
Is it possbile to after reach 78lvl, and made EE/OL, switch to OL and take cert from OL class not from EE ?

Yes it is possible
