The pattern that you're thinking of is "so as to [verb]", so unfortunately your example doesn't make sense. Just use "so I can..." or even better, "and I can only delay it...."
If it's extremely important, why are you able to delay it? :) Perhaps "delay" is the wrong word here.
By the way, the phrase is "grammatically correct". We cannot use "true" in this context. "True" and "correct" are two different concepts.
