Try to use vim.insertModeKeyBindings

[Antonio1C]

Hello! I try to use vim.insertModeKeyBindings. Can I use phrases in block "after"? For example, I need a replacement like this
"vim.insertModeKeyBindings": [
{
"before": ["#", "!", ""],
"after": ["#!/usr/bin/env python"]
}]

It's too complicated to write whole phrase letter by letter.
