Could you suggest me options to this Occupational health scenario?

Hi Friends.

Could you help me?

I have this scenario:

The company hires a clinic to perform test sections and medical examinations.
The company would like to give access to the external user in an occupational health solution in portals, where they could creates the information of the exams and evaluations applied.

1) I researched and it seems that there is no occupational health in portals, is it?

2) What options can you suggest? We thought about:
a) create an authorized external user that manually creates the information of medical services,
b) create a massive data upload program

I saw that there is a standard transaction (EHSDATIMP) for loading results, but the program has no documentation.

Thank you
