Is it possible to get issue entity properties on 'issue update' webhook

[Juan Grases]

For my use case, I would need to identify specific issue updates (performed by REST) when getting the webhook for it. I was thinking maybe there is a way to attach a property to the update, so the webhook would include that property but I believe this is not possible.

The other alternative would be to set an entity property to the issue being updated so I could then look for that property on the received webhook, unfortunately issue properties doesn't seem to be included on the webhook it self. Is there a way to enable them? 

PD: relaying on detecting which user performed the update is not enough for me
