Heredia is likely to be supplemented for the Group 1 Sun Chariot Stakes at Newmarket on 7 October.
The four-year-old recorded a Royal Ascot victory when winning the Sandringham Handicap in 2022 and was subsequently campaigned over six and seven furlongs.
She returned to winning ways with an impressive three-and-three-quarter length success in the Listed Dick Hern Stakes at Haydock Park over a mile and followed up with a success in the Group 3 Atalanta Stakes at Sandown Park.
It would be a first run in a Group 1 for the daughter of Dark Angel if she is supplemented by owners St Albans Bloodstock for the Sun Chariot Stakes at Newmarket's Rowley Mile.
"We've all had a chat and we were absolutely delighted with Sandown," said Richard Brown, racing manager for the owners St Albans Bloodstock.
"She is a filly on a sharp upwards curve and when fillies do that you don't know how far they can go, so we'll most likely supplement her for the Sun Chariot."
