Button to retry (successful) commands for developers

[MoonlightCapital]

It would be so great to have a button to resend a command that was successful in its execution. This is already done with commands when the application does not respond, so why not those that worked?

As a developer, it would help me waste less time when I make incremental changes on a command what want to try it over and over with the same arguments without having to copypaste or type everything again.

Or perhaps, something to instantly bring the whole command arguments to the message send box so that they can be edited in very little time, and at the same time keeping the clipboard for snippets of code.

This could also be a good way to provide users with pre-filled slash commands! I think this is addressing the same pain point as #3929 and #3288, and it would be good to have a feature to fill this gap.
