Event vendors and tokens disapearing before glavier?

Because of we are not getting glavier, is it possible to prolong event vendor and items until glavier is out so we can use them on her gear?

I have been stocking up on books for glavier and now that she is coming later i need to use all of them on character i am not intending to push? And to use books i need to use mats i have been stocking for future.
