How to create multiple IP Addresses on a bonded interface with Netplan?

Edit: This may not be possible. According to the Netplan Docs, aliasing cannot be implemented. If it can't, I suppose I will need to come up with another solution (e.g. use the old interfaces method).

Edit 2: Without using netplan try, and just netplan apply, I'm able to have multiple IP addresses with the same bonded interface (see config below). I will answer my question now.

I am trying to implement a netplan setup with something similar to this old /etc/network/interfaces setup:

However, it appears my syntax is wrong. I have 2 nics on a server, and I'm trying to create multiple IP Addresses on the bond. However, when I use netplan try, it tells me:

bond0: reverting custom parameters for bridges and bonds is not supported

            parameters:

    ethernets:
        eno1: {}
        eno2: {}
    version: 2

Where should the other IP Addresses be placed if it's bonded?
