Generate digital certificates for employees using the organization’s certificate


I live in Peru and we have a small problem in the organization where I work. Dozens of documents are physically signed daily but this is a waste of time since there are documents that must be signed by more than one person and these people are in different geographical locations.

I am thinking of using digital certificates to sign PDFs but this causes me another problem. Certificates are issued in the name of the Organization, not of the employee who signs. Buying (and processing) the generation of a certificate with legal validity for each employee will take time and money so my question is the following:

Is it possible to generate new certificates for each employee (with legal validity) using our institutional certificate as root certificate?
