Those columns are for HyperSpin not RocketLauncher media so to do this properly it would need to be done through plugins since frontend media varies from frontend to frontend and we want RL to be 100% frontend independent. In a nutshell it's a lot of work to do this properly and with good tools already dedicated for that purpose like HyperMint I'd rather focus on other features.
Might happen one day, but it's not on our short term plans.
