Limit to one attempt fitter option gone?

Hello,

There was in the past an option to limit the Quartus fitter to one attempt,

which made the first effort bigger and skip the expected fitting effort to fail:

https://www.intel.com/content/www/us/en/programmable/quartushelp/14.1/mergedProjects/msgs/msgs/ifitapi_fitapi_info_vpr_retry_placement_more_effort.htm

I cannot find this option anymore in Quartus prime standard edition.

I'm asking because my fitting only succeed on the second attempt:

Info (170134): Cannot fit design in device -- retrying with increased optimization that can result in longer processing time
Info (170138): Failed to route the following 9 signal(s)

...

Info (170140): Cannot fit design in device -- following 12 routing resource(s) needed by more than one signal during the last fitting attempt

...

Info (170194): Fitter routing operations ending: elapsed time is 01:07:17
Warning (170136): Design uses Placement Effort Multiplier = 4.0. Using a Placement Effort Multiplier > 1.0 can increase processing time, especially when used during a second or third fitting attempt.

Maybe that the option has been renamed?

Kind Regards,

Alex.
