Overriding existing UTMs

We are running the beta feature – auto append – I assume it is doing the append via Javascript. This is all great and it appears to be working well.

We do have one issue – some of our URLs on our site contain UTMs we want to use to replace the existing one. However, the auto feature is stripping the existing UTM and appending the stored one.

Is it possible to add an option to provide the function of auto append UTM if a UTM does not exist on the URL?

So if URL contains UTM – do not replace UTM
If URL does not have a UTM append UTM

I am interested to hear your thoughts
