Subscribe API call with User Id

We are building an app to make all our employees subscribed to all the apps in our spaces. We have checked the "Subscribe" API and can see this can be done only for the currently autheticated user

https://developers.podio.com/doc/subscriptions/subscribe-22409

It make us very difficult to reach the goal.. is there any way this can be done by the Aministrative user (organization administrators)  login at least.

We are looking at Authenticating as an Admin user and get all the employess and pass the userid also as part of the "Subscribe" API and get that user subscribed.

Is this possible somehow?

Thanks in advance
