Scheduling Tweets straight from Drafts

I quite like using the action that sends Drafts out as a Tweet, as it means you can tweet without opening the Twitter app and then getting distracted. But I’d like to be able to use a similar action to queue Tweets up on a preset schedule. Does anyone know of any actions that allow you to send a Draft straight to a social media scheduling platform (Buffer, Hootsuite, etc) and puts it in the posting queue for Twitter?

Here is an action to send text to the Buffer app.

I have not seen any examples of integrating directly with either Buffer or HootSuite, though it should be possible to script such actions if they have APIs.
