Short answer: no.
Long answer: Don't rely on the Flex Repeater to handle this for you; let your Views do the work with Message Handlers.
Setup:
Let the View being instanced accept a param (like index - this param is passed along free for all instances of the Flex Repeater without you needing to supply anything yourself).
on the ROOT node of the View, configure an onClick event to execute a Script Action with the following code:
system.perspective.sendMessage('ROOTCLICK', payload={'index': self.view.params.index}, scope='page')
Now go to the Flex Repeater, right-click the Flex Repeater, and select "Configure Scripts...".
Under Message Handlers, add a new handler with a message type of "ROOTCLICK", and supply the following code:
self.custom.selected = payload['index']
Now your Flex Repeater is aware of which instance was most recently clicked.
