Please enable the use of placeholders in subjects and message fields on update requests.
I recently found that when you use placeholders (the field names in braces, e.g. {{Project Name}}) in the subject line or the message field of an update request, it sends the default text. This is very problematic because it does not allow you to send your message for context or clarification, and it also accentuates the issues of (1) not being able to mention a field via placeholder (there is a ticket already for that - https://community.smartsheet.com/discussion/110837/read-only-option-in-update-request-and-ability-to-customise?) and (2) include a field in a non-editable format on an update request (any field included can be updated which is confusing).
For context, this is the message I got back from support regarding how it currently works:
Totally agree with this.
