Why can't we place macros with /hotbar ?

[radioactive_lego]

I do not quite understand the question, but I'm guessing you mean placing macros on a hotbar by command, the way justabout any other thing is placable on a hotbar thru command line.

Currently:
　/hotbar [subcommand]

→Edit and configure hotbar settings.

>>Subcommands
　action "action name" [#1] [#2]
　　Set the specified action to slot [#2] in hotbar [#1]. If [#2] is omitted, the action will be set to the lowest-numbered slot available. If both [#1] and [#2] are omitted, the action will be set to the lowest-numbered slot available on the lowest-numbered hotbar available. This applies to all of the following subcommands.
　general "general action name" [#1] [#2]
　　Set the specified general action to slot [#2] in hotbar [#1].
　item "item name" [#1] [#2]
　　Set the specified item to slot [#2] in hotbar [#1].
　emote "emote name" [#1] [#2]
...

Adding:
macro "macro#" [#1] [#2]
Set the specified macro to slot [#2] in hotbar [#1].

would enable macro swapping macros. which was requested here:

only more appropriately addresed in YOUR topic. So thanks for that

Seconded. With every dollar I subscript to this game, and every hour I've played, seconded.
