We have an idea on our Community regarding this: link https://altru.ideas.aha.io/ideas/ALTRU-I-1498. I encourage you to vote on this post as this is an opportunity to have a voice in the product development process. Our Product Management team uses a variety of methods to determine new features in Altru, and the ideas in the Community is one way they do this, so your vote helps Product Management prioritize the new features that we put into the product.
