Linked events from a DE after a specific period of time

[Elessar2]

Been looking over some DE options. I want some to have the secondary linked script (Supply/Unit/Strength/etc.) fire after a specific period of time has passed since the DE came up and Yes (No) was chosen. But apparently the only timing control a scripter has is to just plop down a date, and that is it. So for a DE script whose timing isn't carved into stone (because of Condition Positions and such), the DE could conceivably happen AFTER the other linked script (in which case the latter won't fire at all). IOW I want say a six month delay after Yes has been chosen-any way to put that in there?

Can you chain a dummy event 6 months later that checks the status of the answer of the primary event and if 'true' will then fire the effects you are looking for?
