[FEATURE] - Summit Event Emails - Allow registration variable in Subject Line

[koll2427]

It would be helpful to be able to use a Summit Events registration object variable in the subject line of a Summit Events email. This would allow us to clone Summit Event emails and require less manual editing for every event.

We could put the Event Name in the Subject line without the need to manually type it in each time we clone an email definition.

The work around is to manually type in the Event Name in the Subject Line while setting up the email. We are looking for ways to streamline our process. If we can shave off time in creating these, that would be awesome.

Also, it would be helpful to allow the 'Organization Wide Email' be a variable in the content of the email. We have several senders and it would be easier to reference what we picked as the 'Organization Wide Email' rather than retyping it.

Are you willing and interested in being engaged during the development and testing process?

Yes, I am willing to test these changes.
