Salary merge field to interview invitation email

It would be useful if we could insert the salary merge field in to interview invitation emails so candidates are aware of the salary before deciding to attend an interview.

Most jobseekers apply for more than one vacancy and don't always take note of the salary on offer. In most cases, the vacancy has expired when we're sending out interview emails, so candidates aren't able to check what the salary is. We've experienced quite a few drop outs at point of offer recently due to candidates not remembering the salary on offer and it not meeting their expectations.
