After doing some tinkering, it is possible via:
{
"LogName": "Dynamic Cursors",
"Action": "EditImage",
"Patchmode": "Overlay",
"Target": "LooseSprites/Cursors",
"FromFile": "assets/Dynamic/{{Time}}/Cursors.png",
"SetProperties":{
"CurrentTime": "{{Time}}"
},
"Update": "OnTimeChange",
"When": {
"Time": "0600, 1600"
}
},
Within the content.json file if ContentPatcher is used.
