To be considered for 37F selection, do I need to have my promotable status removed or am I able to still get promoted to E-6?

I'm one year into a three year assignment so I got a little time before I can do anything, but that's where my question comes in. Right now I'm an E-5 promotable. I read on the PYSOP recruiting page that you have to be E-4 or E-5 non-promotable, however on the Army Retention In/Out Calls for 37F it has a Y under In for E-4, E-5, and E-6. So my question is, do I need to have my promotable status removed and stay an E-5 in order to be considered for selection or am I able to still get promoted to E-6 while I'm in this unit (if I pick up) and still be ok? I'm ok with whatever route I need to take, I'm just curious as to what's the right answer.
