I've been very aware that a number of Frog3 schools are disappointed there is no equivalent to Frog Tags in FrogLearn. And I'm told it is something we want to rectify. The ability for schools to display your own personalised data to students inside FrogLearn is an understandably desirable option.
While we work on an internal solution (no ETA I'm afraid), I've prepared a tutorial along with @Chris.Smith (our developer advocate) taking you through all the steps needed to set up a Google Firebase data store, query it from inside FrogLearn and display the results back in a Frog Site.
It looks intimidating, but I've broken it down into straight forward steps for the various stages. Once set up, updating the data becomes a simple task - arguably with fewer steps than updating the data in Frog3's toolkit.
What this means is that you can display any information you choose to upload, so house points, your own rewards system, additional attainment information - anything you can get into a spreadsheet - provided you have a single student identifier in there such as UPN or username. Being a Google product, Firebase is a secure data store - although being a third-party product, you should make that determination for yourself.

I hope this helps.
