Help managing (lot of) missing plugins

I have a lot of tasks not linked to a profile. Several of them have actions that refers to a plugin.
And I use quite a lot Tasker plugins.
Every now and then I have to export/import my whole configuration to a new phone
And until I intercept and install ALL referred plugins, the popup logs will flood me with tens of messages every time I open Tasker.
They are demo/study tasks or historical ones, I want to keep them there, and I want to have the popup log activated.

Need some help to avoid going manually through tens of tasks looking for actions that say "Unknown plugin". Even the search doesn't intercept neither that "Unknown" word nor the "plugin" one. And the popup logs don't show anything useful to understand what missing plugin they are referring to.

Thanks João
