Set UTM source parameter for each social platform?

Set UTM source parameter for each social platform?

I see how you can set UTM parameters in Zoho Social to be applied to all posts.  I would like to specify a different Source parameter that maps to each social platform. 

For example:
For posts published on Facebook, UTM Source = Facebook
But for posts published on LinkedIn, the UTM Source = LInkedIn.
They both should have UTM Medium = Social

I don't think this is possible today, but that's how it should work.  Is there any way to do this that isn't completely manual?  Are there settings for each platform you can specify somewhere?
