Ability to actually invest into Indices

It would be amazing if there was a way to directly invest into the indices that are present on the token metrics app. I had an idea for this a while back and this is the closest I've seen someone get to doing this in crypto.... Is there going to be functionality to support this any time this year? I would love to get exposure to AI crypto for example but want to just invest in an index and not have to worry about individual coins as much, especially considering it is also AI managed & seems to be automatically rebalanced. This is a great functionality to be able to have and is something so common in web2. This needs to happen in web3!!
