Allow data for catalog template uploads
It's often desirable to provide data along with a template that's uploaded to the online catalog. For example, for a table containing how many calories per hour a particular exercise activity burns. Such data exists independently of data the user would be expected to add, and might also be difficult for a user to find and enter themselves. Further, there may be more data than could reasonably be provided as code in a JavaScript field.
Of course, it would be reasonable to also expect a limit to how much data can be provided for the template.

Not sure if this would help your situation.

I'm trying to learn whether triggers are included in catalog uploads. If you don't have the pro version, can you download a library with more than one trigger?
To your point, the developers probably disabled uploading data because people might accidentally upload personal data.
I see they have a planned feature to allow data fill from outside sources. (edit, spelling)
