"5 for 3" Parkhopper with remaining days - Can I still turn it into an AP?

[Vexorg]

Since it was what happened to be available when I bought my pass, I got one of the 5-for3 Parkhoppers for the trip I just completed, even though I only planned to use 3 days. This means I still have two valid days I haven't used. I have now returned home, but I was curious if it would still be possible to apply the pass value to a Premium Annual Pass without actually being in the park as long as it's still valid.
