Add Event Command to custom Donation Amounts

As a streamer I would like to be able to have different commands trigger depending on various donation amounts.

For Example:

$1 Donation - Would run the default chat message and overlay

$5 Donation - would run the default chat message, a new overlay and sound

$10 Donation - would run the default chat message, yet another new overlay and new sound and triggers a command with a webhook...

etc. 

It would also be nice to customize the 'default' donation amounts, maybe having 5 possible options and giving them a title as well as the amount (title to appear under the button)
