Submitting OPM Cost Rollup Program and Cost Update program

Hello Experts,

We are submitting OPM Cost Rollup Program and Cost Update program manually almost every day . We are thinking of scheduling this as overnight batch request but these are all Spawned execution method.

Is there a way to schedule this as single request/ request set. Or can we use some API calls?

Any pointers on this will be really helpful.

Thanks,

Satheesh
