Improving the "Change Multiple Sites' IP Addresses" UI

When changing the IP Address for multiple accounts (imagine 30~40), and if a server has a lot of IPs, the process becomes rather cumbersome and there's a lot of room for human errors. Below are some suggestions I believe would greatly improve the overall experience with this feature in WHM:

• Use "select2" in the list of IP Addresses (probably the easiest to implement) like in cPanel's Account switching when logged in as root/reseller.
• Add an option to apply one IP to all or multiple accounts in one take (checkboxes, please).
• Add an option to apply a reseller's (or the main) shared IP to multiple accounts in one take (yes, checkboxes here too).

Thank you for your consideration.

Notes:

I know that other requests exist:

I hope that the points I made in this particular request offers more clarify on what I, and hopefully other users, would like to see.
