Could we create multiple assets at the same time, maybe with a comma separation Almost allready csv, i know that full csv import and export is planned for later this year.
But would be nice for in the meantime have an option to add more than 1 asset

This would be one for @Innders I think.

And maybe he also has some thoughts on locking out certain characters for entity types as @Yul also requested, etc. But that might go a bit higher into the chain to @milan .
