Voting on items in the Project backlog


I was wondering if it is possible to vote on items in product backlog made with Kanban board in Girea?

I tried to find it but couldn’t.

If not, is there already an issue for it? Could I maybe help implement it? What would it take to add it?

Something similar as Trello has with Voting PowerUp, for example give a look at the Inventaire roadmap

Thanks for you help!
