Add new role/player to crowdfounding platform

Hi all, In crowdfunding there are usually three different roles; the platform itself, the fund raisers and the people who donate.

I’m interested in adding a new role. The validators. Who are in charge of validating that the funding is legitimate and are also the ones who receive the money.

Let me add some context. I want to create a crowdfunding for helping animals. And as everyone knows, there is some risk of people creating fake crowdfunding campaigns. So I want to include vets in the ecosystem. So in order to start receiving money you need some vet who has accredited that the case is real (since always you rise money for an animal shoud be a vet behind). And would be actually the ones who has to receive the money, could you please let me know how I can achieve this with the current features? It is not a problem if I need to do some manuall work by myself since I’m just testing the product.

Thank you in advance.

Kind regards.
