"As the action is announced"

I had a question that came up the other day. Can you play non-"As the action is announced" action modifiers (i.e. Conditioning) in the "As the action is announced" action modifier window (i.e. Seduction)?

Has far as i know, no, if you play a regular action modifier, that windows was close, this avoid that you play cards that are not for that window before cards that rightfully belongs to that time frame

I was thinking yes, but turns out the answer is no - and it's confirmed somewhere in this forum by Ankha IIRC. This results in that you cannot play Conditioning "as the action is announced" and follow it with Seduction.
