I'd like to second this request. In the advanced settings for Autoposts, I tried using the following template:

{link}?utm_campaign=blog&utm_source=twitter&utm_medium=social&utm_content=autopost

For Twitter, it added the tags up to utm_medium=soc then cut off the rest. For Facebook and LinkedIn, it completely ignored the tags. So whether this is able to be incorporated into the post template or as separate fields in the advanced settings, this would be very useful for Analytics geeks like me who try to track everything everywhere!

Thanks for the heads up on this Quinn
