Sharing Bought Assets with Team

Hi there so i have a team of 4-5 people and we want to be able to share bought assets so people can test things out for the area’s they are working on as some are working on levels so would be good for them to have access to all the different level assets we have bought such as tree’s and ground textures other people will be working on weapons and they want to go through all the weapon assets so how can we go about sharing them with the team.

On our central account, we have over 500gb of assets if we have to install everything to a project and upload it to our SVN server that is just insane there must be a way of sharing stuff within a team

any help or advice would be great.
