Enable Activity Webhooks to trigger on Custom Attribute updates in Proxy Votes (and probably other objects).

What is the challenge?

I need to know when a custom attribute in a Proxy Vote has changed.

What is the impact?

We are unable to fully launch our Idea Escalation process with this feature.

Describe your idea

We have a custom attribute for proxy votes, "Priority". This value can change after the vote was created due to multiple factors. When it changes, we may need to update another custom attribute in the Idea that the vote was for. There is a web service this is processing inbound webhooks from Aha that will do the logic to figure out if the Idea attribute needs to change, but won't know about the change if the webhook is not fired when the change is made.
