Pre-Populate CLI Window?

It's nice that CLI QUICKCMD lets you pre-populate the Find-As-You-Type field with a command.

For times when you want a nice, big CLI window, is there an equivalent way of pre-populating the CLI window with a command (without executing it)?
I have tried CLI COMMANDAPPEND and CLI COMMANDSET, but my CLI window stays empty.
Thx. :slight_smile:
