Which options PDMLink have to allow ad hoc access in the containers?

Hi folks,

We need to give access to the partners for a short period of time in their specific parts.

The volume of this operation is high, even for parts that change a lot and the contract with partners.

We already study some options, such as share to project, move parts to other products and manage security, but all options has a high effort to manage.

Someone has the same requirements and use another option?

Tks,
