Hi
If you copy the below to your clipboard and paste into a new flow, I have prepared a scope with a demo:
{"id":"0393a638-eb55-40dc-91d5-ce4d-2e262986","brandColor":"#8C3900","connectionReferences":{},"connectorDisplayName":"Control","icon":"data:image/svg+xml;base64,PHN2ZyB3aWR0aD0iMzIiIGhlaWdodD0iMzIiIHZlcnNpb249IjEuMSIgdmlld0JveD0iMCAwIDMyIDMyIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPg0KIDxwYXRoIGQ9Im0wIDBoMzJ2MzJoLTMyeiIgZmlsbD0iIzhDMzkwMCIvPg0KIDxwYXRoIGQ9Im04IDEwaDE2djEyaC0xNnptMTUgMTF2LTEwaC0xNHYxMHptLTItOHY2aC0xMHYtNnptLTEgNXYtNGgtOHY0eiIgZmlsbD0iI2ZmZiIvPg0KPC9zdmc+DQo=","isTrigger":false,"operationName":"DamoBird365_rename_last_occurrence","operationDefinition":{"type":"Scope","actions":{"String":{"type":"Compose","inputs":"Task: \"x\"; Answer: \"Pending\",\nTask: \"z\"; Answer: \"Pending\",\nTask: \"x\"; Answer: \"Pending\"","runAfter":{}},"LastPosition":{"type":"Compose","inputs":"@lastIndexOf(outputs('String'),'Task: \"x\"; ')","runAfter":{"String":["Succeeded"]}},"LastPositionString":{"type":"Compose","inputs":"@substring(outputs('String'),outputs('LastPosition'))","runAfter":{"LastPosition":["Succeeded"]}},"Replace":{"type":"Compose","inputs":"@replace(outputs('LastPositionString'),'Task: \"x\"; Answer: \"Pending\"', 'Task: \"x\"; Answer: \"Approved\"')","runAfter":{"LastPositionString":["Succeeded"]}},"StartOfString":{"type":"Compose","inputs":"@substring(outputs('String'),0,outputs('LastPosition'))","runAfter":{"Replace":["Succeeded"]}},"Concat":{"type":"Compose","inputs":"@concat(outputs('StartOfString'),outputs('Replace'))","runAfter":{"StartOfString":["Succeeded"]}}},"runAfter":{}}}
Using LastIndexOf, you can get the last occurence of the string you want to replace, replace the value on the substring and then concat the original start of the string with the substring that you have replaced. I have overexagerated the solution by including all steps but this could be simplified to reduce the number of actions.
