I would like to attach some buttons to the bottom of the TG channel, as a shortcut to save time on typing.

I'm using bot.send_message() with parameters chat_id, text, parse_mode, reply_markup.
The reply_markup code is about like this:

To ensure the buttons are there, also when the bot restarts, is added to a channel etc, I set them for every message sent by the bot.
The buttons do appear in the channel, but the original bot message is included as a quotes message that the a button press replies to.

Can I change this, so the buttons are just shortcuts for commands, and not replies to specific bot messages?
