[ implemented - solved ] Suggest - Mass Edit in Background

[rslemer]

Some operation, like a mass edit, for many records, causes overloading in server or freeze the screen until all operations is done.

For example, import spreadsheet, in CSV,  have a same problem, but is system do a intelligent solution, for import in batch mode, in background.

I suggest, when mass edit, for many record, use a same mechanism, and to causes much minor impact in system.
