[feature] Data source display allows setting aliases

[longzmkm]

Can I set an alias for the source? Maintain a dictionary to control the displayed names. Otherwise, the IP and port cannot immediately let people know where this table is located.
There are too many databases and tables, I can't remember the IP and port
If tables and jobs can also be set with aliases and support search, that would be even better
