link " Build detail " to "economical overview"

When I open build detail I will not see the 12h production time. I have 40 farms split in different prod units [ without silo / with Silo / with Improved Silo ] - When I consult Eco overview, after long checking I will find that build + sub group builds and the subtotal 12h production = the link is only 1 way = from eco overview towards indivual build !!
Could be nice to have that link both ways = thus also from Build detail towards the eco overview !! This would speedup the knowledge/calculation of the TSO 12Hour production - of course I know the Swedisch deposit calculator [ great asset ] but I believe TSO could help by creating the 2nd link.
Thanks for reading and giving positive feedback !!
