Current version of form "Asset types" can't working correctly with large scale of job types.
When you have around 40000 job types the form will open about 5 minutes, because of sort out choosen and not choosen job types. And there is no variants to limit the sample, unlike a simple grid. Som working with form becoming hard.
It is not possible to remove enumeration, because the class has mark "final".
I propose to improve the job selection control.
