Possible to set a field value for a file that is not used as a template?

So I am setting up a file to be used to process data. The url to this template will have post data that I need to do a 50/50 split on what to do with the data. Think of it as a cron job...

Before adding a custom db table which is one way I thought about determining what to do with the data based on if a field is true or false, and after processing the data, update that value to true or false...

Is there a way I can create a custom field and update the value of that field for a custom file that is not used as a template in PW? 

My thought would be to dynamically create the field if the field does not exist... that way I won't need to create the custom field in the dashboard. If the value does not exist create it. This is because I will be using this same template file on 5 different websites which are just different locations for the same website.

So template is cron.php in /site/templates/cron.php I would like to create a field called cron with a value of true or false. After processing the data update the field to true or false.

Well for now I just decided to use it as an actual template and create an actual field for the 50/50 split updating. Seems to be working fine. I guess I can keep this hidden and unpublished.
