Can I add PH to 10 day non-expiring ticket?

[flowerfairy]

i purchased 2 10-day WP&M non-expiring tickets from Undercover Tourist around the time Disney was discontinuing the sale of no expiration tickets. I realized recently that they are not PH tickets. Can I upgrade these to PH's or am I just out of luck?

Several posters said that they could add that kind of upgrade.

Adding "days" to never-used Non-expiring tickets is not allowed.
(Of course, with a 10-day ticket, adding "days" was never allowed, anyway.)
