Describe the solution you'd like

I'd like a reactions variable available in shortcuts to be able to filter based on the reactions a memo has

Type of feature

User Interface (UI)

Additional context

I'm trying to use memos like a kanban-like board, where all the tasks have the task tag and "To Do" "In Progress" and "Done" are marked with a reaction. no reaction means "To Do", "⏳" means "In Progress" and "✅" means done
