Time/effort estimation at initiative (not card) level

[Stacey]

Hello!

Wondering if anyone could point me in the right direction for a trello power-up that will allow to set estimates / actuals for both actual work hours spent, as well as days passed at the card level, but also at a higher level group of cards that will allow tracking / assessment of managing features/initiatives delivery? We have only been able to find at card level so far..

Thanks!
