Pierrocity acquitted herself well in her first attempt at a middle distance when runner-up over 2100m at Pukekohe Park at her latest start.
"She'll run next on April 21 in the Valachi Downs Champion Stakes," Marsh said.
"She'll have blinkers on and I believe she's still on track.
"There's a flight on May 4 and if they go they will both run in the Doomben Roses and then the Queensland Oaks."
The fillies will join their stablemate Chocante, who arrived safe and sound in Sydney earlier this week before travelling on to Brisbane.
He was due to have an outing in the open sprint at Te Aroha last Saturday, but Marsh decided against running the son of Shocking.
Last year's group two Brisbane Cup (2200m) winner will run in the Listed Tails Stakes (1600m) at Doomben on April 21 followed by the group two Hollindale Stakes (1800m) at the Gold Coast two weeks later and then the group one Doomben Cup (2000m) on May 19.
