As you said yourself, this is what the template option is for. That is why I don't think it is worth adding it. You can do it with the following one line:
Code:
program:
add(re(raw_field('#my_int_column'), 'None', 0), 1)
The number in
blue is the increment.
Update: As of calibre 5.13, template language supports several operator types including arithmetic operators. So people using calibre version >= 5.13 can replace the above code with this:
Code:
program:
re($$#testint,'None','0') + 1
