Back in the olden days when I was looking for an airline job, most potential employers used to state in the application criteria "xxxx hours multi engine command time (excluding centreline thrust aeroplanes)".Pretty self explanatory, really: Pushme-Pullyou time was excluded by some employers.
Having said that - in Oz I would still have logged C337 time as multi (had I flown it), but simply deducted it from my total for an employer who excluded it.
