Change default Stop-Action of vApp

Hello,

is it possible to  change the default stop-action of a vm from "Power off" to "Shutdown" within a vApp ? In 99.9 % of the vapps we (or our customers) have to do this manually. that is a little bit annoying. It could be done with AMQP & vCenter Orchestrator, but maybe there is some configuration parameter i am not seeing ?

Thanks in advance
