Zabbix UserParameters in agent configuration file support flexible parameters by using UserParameter=key[*],command syntax.

It would be very useful to have the same approach for Alias setting in agent configuration file because currently Alias accepts only hardcoded item keys with all macros (e.g. LLD) already manually resolved.

This issue originally is an attempt to find a vague workaround for ZBXNEXT-1606 and ZBXNEXT-3205.

Example:

# This works as expected currently
Alias=vfs.fs.discovery.1:vfs.fs.discovery

# This does not work currently and should accept all resolved LLD macros and key parameters from server
Alias=vfs.fs.size.1[*]:vfs.fs.size[*]
