Manual frontend scripting was introduced in  ZBX-8121 and it's a great feature.

On this request a new macro {MANUALINPUT} was provided and from my observations it's an unusual macro. All built-in macros in Zabbix have syntax like {MACRO.ACTION} (like below):

so macro for global scripts should be renamed to {MANUAL.INPUT} to keep a direct syntax.

I would like to add another feature for global scripts.

It would be nice and very useful to keep global script page "as clean as possible", so providing feature like multiple inputs to manual scripts should be useful to keep zabbix very flexible. So if it would be possible then macro {MANUAL.INPUT} could be indexed just like e.g {HOST.HOST} or {HOST.DNS}.
