Data binding tool for Creatio. Bind to 3rd party package

Hello,

We use 'Data binding tool for Creatio' to bind lookups and other data to their 'data package'.

And when we bind data, the tool offers to choose one of packages. By unknown reason there are also 3rd party packages offered. And it is possible accidentally to bind data to them and not possible to delete from such packages after.

What is the filtration condition to display/hide packages in this tool?

Thank you!
