Why don't we have a way to easily detect ADD or EDIT mode when opening a Form - like this?

In email body or template we can use the variable shown below.  There are many use cases on a From view where we need to take different actions based on if the Form is being used to add a new row or if it is being used to Edit an existing row.

It seems extremely odd to me that we have an email variable to be able to report if the mode was ADD or EDIT/UPDATE but we don't have that capability to easily do the same in a Form View.  The only way I know to detect this mode is based on if the row exists in the table or not - i.e. on an ADD it will not yet exist in the table.

It would be so much easier and more reliable if we could ask the app what mode it thinks its in!

Have I been missing something all these years?
