Hello javacentric -
Apologies for the delay of our response, unfortunately, we are not typically available to respond to posts over the weekend.
No - there is no way to bulk revise templates on active listings and the steps I have provided are currently the only means of doing so without ending a listing and then reposting it after it has been revised in Saved. Due to the variety of ways in which templates can be added to listings and that listings can be edited on eBay after they have been posted, there are a variety of factors that make building such a tool that would be effective in most template circumstances more complex for active listings.
The circumstances surrounding the change to the links policy and, as a result, the use of the supersize page were different than other changes eBay has recently required and we needed to ensure that our solution was compliant with eBay while providing a very similar experience for the supersized image function. Unfortunately in this case, those changes took a bit longer than anticipated and hence the timing difficulty.
We expect to have the remainder of the templates updated with the supersize functionality in the very near future and apologize again for the difficulties represented by this issue.
