Not possible with the built-in scheduler, unfortunately.
Reasonably easy to set up using an external scheduler though (assuming you have a suitable external scheduler, or at least can install/set one up).
There are various tools that can start Sense tasks from command line, or by using messaging queue protocols (my own Butler service does this - works really well also for large/enterprise environments, more info at https://mountaindude.github.io/butler )
There is also at least one tool on branch.qlik.com that provide similar feature form the Windows command line.
A command line tool is prob the easiest way to get started if you will only use this in a Windows environment, if you on the other hand would like to trigger reload tasks from other systems/platforms (Linux etc), you want a messaging queue/pubsub solution, for example using MQTT).
