WTH, can't manually add more insights to energy tab

I’ve made a some extra sensors:

Load balance (grid vs solar)
Live solar production
Total energy cost savings trough solar consumption

It’d be nice to add them to the Energy tab as right now I just made a separate dashboard to be able to include them. Also, the above sensors would be very useful if they’d be included as standard in the energy tab instead of having to make them yourself. The last one will be a pain in the backside to rewrite the formula everytime the energy tariffs change over time.
