tl:dr, exactly as board_name quest, I couldn't manage to send a push request, but I'd have tried to clone the board_name to memorial_name

Checklist

Checklist for quest suggestions (see guidelines):

• 🚧 To be added tag is established and has a useful purpose
• 🤔 Any answer the user can give must have an equivalent tagging (Quest should not reappear to other users when solved by one)
• 🐿️ Easily answerable by any pedestrian from the outside but a survey is necessary
• 💤 Not an overwhelming percentage of quests have the same answer (No spam)
• 🕓 Applies to a reasonable number of map data (Worth the effort)

Ideas for implementation

like /src/main/java/de/westnordost/streetcomplete/quests/board_name/AddBoardName.kt

eventually extended to similar pois
