Is there a way to delete older versions of a constant using a process model?

HI All,

Is there a way to delete older versions of a constant using any appian function or smart service?

Scenario: I'm calling an API to get the bearer token and storing it in a constant. This is done using a recurring job (PM every 10 mins). But, doing this its creating a version every 10 mins. Is there any way to delete older version systematically?

FYI, 

I understand we can to an alternate approach by storing the value in a db and updating it, But I would like to see if there is any way to delete the older version of the constants.
