Read and write options in adobe campaign workflow

Hello!

For a query in a workflow, I'm trying to save a "last run date" in the options. That's why I need to read this option, start a new query using the value in the option and save a new value for the option back to the system.

So my question is:

What is the best way to read and store system options in Adobe Campaign (my company -> platform -> options).

is there a specific JavaScript (API) Method to get/write options?

Best regards,

Alex
